This photograph of the Treaty Room by Abbie Rowe was taken on August 10, 1948 during the Harry S. Truman administration. The Treaty Room, located on the Second Floor of the Executive Mansion, has held many names and purposes for first families over the years. Today the room is used as a private study for the president and is often redecorated with each administration, but in 1948 President Truman's daughter Margaret used it as a sitting room.
