Amazing DH-4 Crash Photo Collection - circa 1920's

A large group of 45, 4.5x3.5" b&w photos of crashed DH-4's (plus two smaller at 4.25x2.5"). Most are marked in ink or pencil on the reverse: "Brooks Field" and several have the names of the crashing pilots and observers! Light remnants of old glue on the back. In general very good condition.
