This original postcard is from the 1933 Century Of Progress (Chicago World's Fair) which was held in Chicago. It is in very good condition and the front features the "Avenue Of Flags". The reverse side features a postcard format, which is unused and a paragraph that says "Avenue of Flags, stretching from the main gates of A Century of Progress at Twelfth Street, to the north entrance of the Hall of Science..a fitting promenade leading to the wonders of this great Exposition" and measures approx. 3 1/2" x 5 1/2".
