smallest of the federal visual arts projects conceived under the New Deal to help Depression-stricken American artists in the 1930s. It was directed by the painter Olin Dows and designed to embellish existing federal buildings that lacked construction appropriations to finance such works.

It was operated under the procedures of the U.S. Department of the Treasury Section and funded by the Works Progress (later Projects) Administration (WPA), producing 89 murals, 65 sculptures, and about 10,000 easel works for $873,784 between 1935 and 1939. Ninety percent of TRAP's employees were on relief and worked under nonrelief master artists such as Reginald Marsh (Marsh, Reginald), whose frescoes in the dome of New York City's Custom House are the project's most distinguished achievement.
