1936, Louis A. Simon, Supervising Architect of the U.S. Treasury. 200 W. Main St.
Similar to many other one-story Colonial Revival post offices erected under Simon's tenure as supervising architect, the five-bay brick structure with its central entrance set in a slightly recessed segmental arch has a louvered cupola. In contrast to the rather bland exterior, the interior WPA murals, Sheep—Mother and Child—Cow and Mining (1940), by William H. Calfee of Chevy Chase, Maryland, while alluding to the county's economy, could be viewed as alarming. The larger one sets a heroic-scaled woman and her child in a bucolic setting with gigantic sheep and a worried-looking cow; the smaller painting depicts two men standing in front of an askew mine entrance that seems to be an enticing trap.
