The 50-cent stamp depicts the Arlington Amphitheater. The Amphitheater, completed in 1920, is located in Arlington National Cemetery, across the Potomac River from Washington, District of Columbia. An image of the original Tomb of the Unknown Soldier occupies the stamp's foreground. The tomb holds the remains of an unidentified WW I American soldier who was entombed on Armistice Day, November 11, 1921. This simple tomb was covered in 1931 by the more elaborate marble sarcophagus familiar today. The stamp was issued in Washington, D.C., on November 11, 1922, the first anniversary of the soldier's entombment.
Clair Aubrey Huston, who designed the stamp, based his work on a photograph. The vignette was engraved by Louis Schofield. Edward E. Myers engraved the words “Arlington Amphitheatre.” Edward E. Myers. Edward M. Hall and Joachim C. Benzing engraved the frame.
Initially printed on the flat plate press, the stamp was also printed on the Stickney rotary press.
