United States Post Office (Sweetwater County Historical Museum), Green River, Wyoming.

This classic U.S. Post Office building in Green River, Wyoming was built in 1931 in the classic Greek Revival style then popular for Federal buildings. The structure now houses the Sweetwater County Historical Museum.  Directly across the street from the Sweetwater County Courthouse, I thought at the time I photographed it (poorly) that it might have housed a Federal courthouse, as some posts offices did, but that does not appear to be the case for this one.

Basin Wyoming Post Office

This is a bit outside of our unusual topic here (which admittedly has been expanding) but this is an unusually nice and classic small town U. S. Post Office.  This is the very classically styled Post Office in Basin, Wyoming, which is right next to the classically styled Big Horn County Courthouse.

That such an impressive, albeit small, structure was built shows how viable and important these small towns were.
