Original 1947 AP wire photo showing Cpl. Harlen Plummer exercising on a treadmill while Sgt. Harold Buffinbarger rests inside a 25-below-zero chamber at Wright Field in Dayton, Ohio. The men were spending 10 days in the artificial Arctic chamber while testing Arctic rations. The caption is printed directly on the photo. Measures approximately 5¼x7¼ inches. AP stamp on the back. Note the tape on the corners, areas of emulsion loss and typical newsroom/archive wear. Came from the archive of a Pittsburgh-area newspaper.
