Holy awesome photo. This one was labeled as the Washington Monument on Armistice Night, November 25th, 1921. We posted another Armistice-related photo a while back, but this one beats it. What a terrific photo, and a vastly different Washington Monument than this one, used as a slaughterhouse and beef depot, before it was completed.
Photograph shows lights beaming from the top of the Washington Monument at night, also large lights on the ground, directed up, illuminating the sides.
