L. Clark Schilder, the Warden of the Federal Reformatory in El Reno, Oklahoma, wrote this letter to President Truman and enclosed a gift for him. The "slogan plate" that Mr. Schilder refers to is the "Buck Stops Here" sign that President Truman put on his desk. Mr. Schilder sent the sign to President Truman at the suggestion of President Truman's friend and former employee, Fred Canfil, who served as a United States Marshal. From the Harry S. Truman Papers, President's Personal File.
