This original postcard is from the 1933 Century Of Progress (Chicago World's Fair) which was held in Chicago. It is in excellent condition and the front features the "Three Fluted Towers". The reverse side features a postcard format, which is unused and a paragraph that says "These three fluted towers 150 feet high around the dome of the Federal Building represent the three branches of Government-Administrative, Legislative & Executive. The towers are illuminated at night" and measures approx. 3 1/2" x 5 1/2".
