The collection contains 2x3" photographs of military personnel, possibly from a fighter squadron, and aircraft, circa 1939-1945. The images do not include contextual information or captions. It is unknown if John Hoagland was the photographer or if he collected these images.

The Paul A. Ludwig Military Aviation Photograph Collection contains 2382 photographic prints and negatives with a very small amount of textual materials collected by Paul A. Ludwig and ranging from the late 1910s through the early 1980s. The bulk and strength of the collection is photographs of World War II-era aircraft and squadrons. The collection is nearly all copy prints from a variety of institutions and dozens of private collections.
