The reverse of a 1937 snapshot from the Rudy F. Majewsky collection, handwritten to identify the Panama Air Depot barracks, hospital building, and the 25th Bombardment Squadron building at France Field in the Panama Canal Zone. Such personal annotations, common among U.S. Army Air Corps personnel of the era, help modern researchers precisely identify structures and units at this strategically vital airfield, which defended the Panama Canal during the interwar and WWII years.
