The one-story five-bay tawny brick post office with a red-tiled hipped roof with exposed rafter tails has segmental arches over the rectangular windows, creating a vaguely Mediterranean residential character rather than the Colonial Revival or Moderne styles typical of Simon’s tenure. The post office houses the 1942 mural Lumber Manufacturing by Dallas-based artist Jerry Bywaters, which depicts an important regional industry. The mural was funded by the Section of Fine Arts of the U.S. Treasury.
