Most of the post office works of art were funded under the Treasury Department's Section commissions. Those works that were created using TRAP funds are so indicated. Although the WPA funded the construction of post office buildings, the artwork was not WPA but was usually produced under the Section or TRAP programs.

Many thanks to Jimmy Emerson who contributed the photograph.
