This original postcard is from the 1933 Century Of Progress (Chicago World's Fair) which was held in Chicago. It is in good condition but has a slight crease and a slight tear at the top of the postcard and the front features the "Rocket Cars Crossing Lagoon". The reverse side features a postcard format, which is unused and a paragraph that states "Here is the supreme thrill of a lifetime- a ride on the Sky Ride" and measures approx. 3 1/2" x 5 1/2"
