The mural program that commissioned Ralph Stackpole's work was the Treasury Section of Painting and Sculpture, commonly called the Section. It operated under the U.S. Treasury Department from 1934 to 1943. Stackpole served as a lead artist on the Coit Tower murals in San Francisco, a Public Works of Art Project (PWAP) commission in 1934. The Section then hired him in 1936 for a separate federal mural commission, so two New Deal programs touched his career at different moments.
Sorting out which program commissioned which Stackpole mural trips up most short explainers. The confusion is structural, not trivial. Stackpole worked for at least three overlapping federal art programs between 1933 and 1939, and each one ran on different rules. Getting the attribution right requires understanding how those programs differed in funding, oversight, and artist selection.
The layered federal art bureaucracy
The New Deal did not create one mural program. It created several, and they competed for the same artists. The Public Works of Art Project ran from December 1933 to June 1934 under the Treasury Department. It was a relief program first and an art program second. The PWAP paid artists weekly wages to decorate public buildings, and it dissolved quickly.
The Treasury Section of Painting and Sculpture replaced the PWAP's model with something more permanent. Created in October 1934, the Section awarded commissions through anonymous competitions judged by regional committees. Artists did not apply for wages. They competed for specific walls in specific buildings, usually post offices and federal courthouses.
A third program, the Treasury Relief Art Project (TRAP), ran from 1935 to 1939 and hired unemployed artists to decorate existing federal buildings. The Works Progress Administration's Federal Art Project, launched in 1935, was the largest and most decentralized of the four. It funded thousands of murals through state and local sponsors rather than Washington competitions.
The key distinction: the Section bought art for federal buildings, while the WPA and TRAP mainly paid artists' salaries. That difference determines who gets credited as the commissioning program on any given Stackpole mural.
Why the Coit Tower murals belong to the PWAP, not the Section
The Coit Tower frescoes are the most famous murals associated with Stackpole, and they are routinely misattributed to the Section. The project began in late 1933 under PWAP sponsorship. Stackpole was one of the artists who pitched the idea of decorating the interior of the newly built Coit Memorial Tower on Telegraph Hill.
The PWAP funded 25 artists to paint the tower's interior in 1934. Stackpole painted the California Agriculture panel and helped organize the crew. His son, Peter Stackpole, photographed the project. The program's relief structure meant artists received weekly paychecks, roughly USD 35 to USD 45 per week depending on skill classification, rather than competitive commissions.
The Coit Tower project ended in controversy in July 1934. Conservative groups objected to leftist imagery, and some frescoes were altered or covered. The PWAP itself shut down that same month. No Section money touched the tower. Anyone who tells you the Section commissioned the Coit Tower murals has collapsed two programs into one.
This matters beyond trivia. The Coit Tower episode shaped how federal officials designed later programs. The Section's competition system and its vetting of sketch designs were direct responses to the political blowback the PWAP suffered in San Francisco.
Stackpole's Section commission and the selection mechanism
After the PWAP dissolved, Stackpole continued working through transitional relief programs. In 1936 the Treasury Section awarded him a mural commission for the San Francisco Mint, a federal building. This is the commission that properly belongs to the Section.
The Section's mechanism differed from PWAP relief in three ways. First, artists submitted designs anonymously, and juries judged the sketches without knowing who made them. Second, the Section paid a fixed fee based on the wall's square footage, not a weekly wage. Third, the Section retained approval rights over the finished fresco, and artists could be required to revise work that failed review.
The anonymity rule was the Section's signature innovation. Officials believed it would insulate competitions from political pressure and favoritism. In practice, established artists still won disproportionately because jurors recognized styles. Stackpole's reputation from Coit Tower gave his submissions weight even under blind review.
One counterintuitive detail: the Section's fees were often lower than PWAP wages for comparable time. A Section muralist might earn USD 500 to USD 1,500 for months of fresco work, while a PWAP artist drew a steady paycheck. The prestige of a permanent federal commission offset the lower pay, at least in theory.
Sorting the programs: a comparison
The table below maps the four programs that touched Stackpole's era. Use it to check any attribution claim against the program's funding source and selection method.
| Program | Active years | Funding model | Artist selection | Stackpole connection |
|---|---|---|---|---|
| Public Works of Art Project (PWAP) | 1933–1934 | Weekly relief wages | Local committees | Coit Tower murals, 1934 |
| Treasury Section of Painting and Sculpture | 1934–1943 | Fixed commission fees | Anonymous competitions | San Francisco Mint mural, 1936 |
| Treasury Relief Art Project (TRAP) | 1935–1939 | Relief wages for existing buildings | Section oversight | Indirect, through Bay Area projects |
| WPA Federal Art Project | 1935–1943 | Salaried employment | State and local sponsors | Bay Area teaching and studio work |
The takeaway is simple. If the mural sits in a building the federal government owned and the artist won a competition, it is probably a Section commission. If the mural was painted by a relief-paid crew in a city or state building, it likely traces to the PWAP or WPA.
Timeline: how the attribution question took shape
The historical record accumulated in stages, which is why misattributions persist. The timeline below tracks the key dates.
| Year | Event | Attribution impact |
|---|---|---|
| 1933 | PWAP launches under Treasury | Coit Tower planning begins |
| 1934 | Coit Tower murals painted and contested | PWAP credit established |
| 1934 | PWAP dissolved; Section created | Program transition confuses later accounts |
| 1935 | WPA and TRAP begin operations | Overlapping programs multiply crediting errors |
| 1936 | Section commissions Stackpole's Mint mural | Section credit established |
| 1943 | Section and WPA art programs wind down | Records scattered to archives |
| 1960s–1970s | New Deal art scholarship expands | Retrospective catalogs begin correcting credits |
The scattering of records after 1943 is the root cause of most errors. Section files went to the National Archives, while WPA art records were distributed among state agencies. Researchers who consult only one archive see only part of the picture.
Misconceptions and red flags
Several recurring errors distort the answer to which program commissioned Stackpole's murals. Watch for these warning signs in secondary sources.
Attributing Coit Tower to the Section. The tower predates the Section and was funded by the PWAP. Treating the WPA as the umbrella for all New Deal art. The WPA's Federal Art Project was one of four separate programs. Assuming one artist worked for one program. Stackpole moved among PWAP, Section, and WPA-funded teaching roles across six years. Citing undated sources. Program names changed, and a 1933 credit may be accurate while a 1936 credit for the same wall is not. Conflating the Treasury Department's art units. The Section and TRAP both sat under Treasury but ran on different money. Trusting museum labels without checking accession records. Labels often simplify program names for visitors.
The single most common red flag is a source that calls Coit Tower a "Treasury Section" project. That phrase alone indicates the writer has merged the 1934 relief program with the 1934–1943 commission program.
Practical steps for verifying a Stackpole attribution
If you need a defensible answer for research, a label, or a publication, work through the records in a fixed order. The steps below reflect how professional art historians resolve New Deal credits.
First, identify the building's owner in the relevant year. Federal ownership points to the Section or TRAP. Municipal or state ownership points to the PWAP, WPA, or a local sponsor.
Second, pull the building's construction and decoration dates. A mural painted before June 1934 cannot be a Section commission, because the Section did not exist yet.
Third, search the National Archives Record Group 121 for Section files. Section commission records include competition entries, jury notes, and payment vouchers that name the artist.
Fourth, check the WPA Federal Art Project records held by the National Archives and state archives. These include employment rolls that show whether Stackpole drew a salary during the mural's production window.
Fifth, cross-reference with the Fine Arts Museums of San Francisco and the San Francisco Art Commission, which hold local documentation on Coit Tower and Mint projects.
Sixth, treat any single secondary source as provisional until it names the program, the funding year, and the selection method. A credible citation does all three.
The threshold for confidence is straightforward. You have a defensible attribution when the program name, the commission year, and the payment mechanism all match the primary record. If any one of those three is missing, the attribution is still a hypothesis.
Limitations and the honest edge of the record
The documentary record has real gaps. Some Section competition files were lost, and some WPA employment records were discarded when state offices closed. Stackpole's own papers, held in California archives, cover his career unevenly. The Coit Tower period is well documented because of the 1934 controversy, but the Mint commission has thinner coverage.
A second limitation is definitional. "Commissioned" can mean funded, selected, or supervised, and different programs did different combinations of those things. The Section both selected and paid Stackpole. The PWAP paid him as an employee of a relief project. Both are commissions in ordinary usage, but they are not the same kind of transaction.
A third limitation concerns scope. Stackpole also executed works for churches, private patrons, and civic groups in San Francisco. Those commissions have no federal program behind them at all. A question about "which program" only applies to his federally supported murals.
The most defensible short answer remains this: the Treasury Section of Painting and Sculpture commissioned Stackpole's federal building mural at the San Francisco Mint in 1936, while the earlier Coit Tower murals came through the Public Works of Art Project in 1934. Any account that assigns both projects to one program has flattened a genuine administrative distinction.
Readers researching New Deal art attribution for publication, museum work, or historical preservation should consult archival records directly rather than relying on summaries. This article provides general historical information, not a certified provenance determination. For formal attribution questions, consult a qualified art historian or archivist with access to the relevant National Archives holdings.
