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 "The Field Museum of Natural History, Chicago". The reverse side features a postcard format, which is unused and a paragraph that says "A most unique view of the Field Museum and not an aerial. This view has never been published before & surely is a wonderful view of this worthy Institution" and measures approx. 5 1/2" x 3 1/2".
