Aircraft belong to the 112th Observation Squadron. Serials are 30-418, and 31-349. First plane carries no extra markings other than the insignia of Ohio’s 37th Infantry Division. This leads me to believe the aircraft was recently painted or overhauled. All their wheels are muddy, so you know what their runway is made of. The photo is almost 2 x 2 feet – must have hung on a squadron wall somewhere back when.
