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 with slightly worn corners and the front features the "Old Heidelberg". The reverse side features a postcard format, which is unused and a paragraph that says "Seating Thirty-five hundred persons, this restaurant is a replica of the Old Heidelberg Inn located in Heidelberg, Germany noted for its food & beer the world over" and measures approx. 5 1/2" x 3 1/2".
