Abstract Postcards collected and photographs taken by Allen Truax and wife of historic sites related to the American Revolution, done from the 1930s into the 1950s. The collection is organized by state, plus Canada, and then by town or specific site. Collected as part of the writing of his unpublished typewritten manuscript entitled "Guide to the American Revolution" , modeled upon Benson J. Lossing's Pictorial Field Book of the Revolution (1857).
