This item is the reverse side of an archival photograph, bearing a handwritten notation, 'Curtiss P-40 N - 5-26-43,' identifying the subject of the corresponding front-side image as a Curtiss P-40N Warhawk photographed on May 26, 1943. This date places the original photograph squarely within the height of World War II, when the P-40N -- the most numerous production variant of the Warhawk series -- was in widespread service with U.S. Army Air Forces units around the world.
