The U.S. Post Office in Prosser, Washington, is a single-story brick building completed in 1935 as part of Depression-era federal construction projects. Designed in the Moderne style—specifically exemplifying the stripped classicism typical of New Deal government architecture—the structure stands on East Meade Avenue in downtown Prosser. Its most celebrated feature is a lobby mural titled "Mail Train in the 80's," painted by Ernest Norling in 1937, which commemorates mail delivery at the Northern Pacific railway depot during the 1880s. Norling, a PWAP artist from Pasco, became known for his New Deal murals throughout the Pacific Northwest. The building was recognized as a historic landmark when it was added to the National Register of Historic Places in 1991.
