This composite tribute photograph honors three Army Air Corps officers - 1st Lts. Bruce T. Marshall, Lawrence E. Bennett, and Carl A. Carlson - in connection with B-29 Superfortress serial number 45-21848 and the date 29 May 1947. Memorial composites of this kind were often created following an aviation accident or significant unit milestone in the earliest postwar years of American military aviation, just before the Army Air Forces became the independent U.S. Air Force later that year.
