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 "Black Forest, Chicago World's Fair". The reverse side features a postcard format, which is unused and a paragraph that says "A section showing the ice skating pond in the foreground, one of the buildings and the mountains in the background" and measures approx. 5 1/2" x 3 1/2".
