Built in 1936, the Hoisington U.S. Post Office is an example of the Classic Revival architecture commonly repeated in post offices across the country in the 1930s. The one-story, gable-roofed, red brick building features a transomed double door with a wooden classical surround on the north façade. It features an original painted vestibule, original tile floors and wainscoting and original painted surrounds of the postmaster’s door and bulletin board. The historic “Wheat Center” mural, part of the U. S. Treasury Department’s Section of Painting and Sculpture program, is installed on the east wall of the lobby. The Post Office Building and the ”Wheat Center” mural were listed on the National Register of Historic Places on October 17, 1989.
