The Herman Butler Collection contains correspondence, photographs, and ephemera relating to the World War I career of Herman Butler. Letters and postcards from Butler to his aunt and uncle along with a collection of black and white photographs trace his wartime activities from training in California to travel across the country to New York, shipping out to England, service in France, and postwar service in Virginia. Additional materials include military and wartime ephemera, the bulk of which is from the U.S.A. School of Aerial Photography in Langley Field, Virginia.
