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 but has a slight stain near the lower left corner on the back of the postcard and the front features the "Czechoslovakian Building, Chicago World's Fair". The reverse side features a postcard format, which is unused and measures approx. 5 1/2" x 3 1/2".
