The purpose of the PWAP was "to give work to artists by arranging to have competent representatives of the profession embellish public buildings." Artists were told that the subject matter had to be related to the "American scene". Artworks from the project were shown or incorporated into a variety of locations, including the White House and House of Representatives. Artists participating in the project were paid wages of $38 – $46.50 per week. Participants were required to be professional artists, and in total, 3,749 artists were hired, and 15,663 works were produced. The project was succeeded by the Federal Art Project of the Works Progress Administration.
Another significant project funded by PWAP is the Astronomers Monument at Griffith Observatory in Los Angeles. The monument is a large outdoor concrete sculpture on the front lawn of the Observatory that pays homage to six of the greatest astronomers of all time: Hipparchus ; Nicholas Copernicus ; Galileo Galilei ; Johannes Kepler ; Isaac Newton ; and William Herschel. Soon after the PWAP began in December 1933, in cooperation with the Los Angeles Park Commission, PWAP commissioned a sculpture project on the grounds of the new Griffith Observatory. Using a design by local artist Archibald Garner and materials donated by the Women's' Auxiliary of the Los Angeles Chamber of Commerce, Garner and five other artists sculpted and cast the concrete monument and figures. Each artist was responsible for sculpting one astronomer; one of the artists, George Stanley, was also the creator of the famous "Oscar" statuette presented at the Academy Awards. On November 25, 1934, about six months prior to the opening of the Observatory, a celebration took place to mark completion of the Astronomers Monument. The only "signature" on the Astronomers Monument is "PWAP 1934" referring to the program which funded the project and the year it was completed.
''Muse of Music, Dance, Drama''
This Art Deco style monument serves as the gateway to the Hollywood Bowl, and is said to be the largest of hundreds of monuments in Southern California constructed under the WPA. The 200-foot long, 22-foot high sculpture is also a fountain and was constructed with concrete and covered with slabs of decorative granite. The structure was completed in 1940 by George Stanley, also a contributor to the Griffith Observatory's Astronomers Monument and who is better known as the sculptor who molded the original Academy Awards' Oscar statue. The structure was refurbished in 2006.
