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 slight wear and the front features the "Sky Ride". The reverse side features a postcard format, which is unused and a paragraph that says "This is the Sky Ride, the most spectacular feature of Chicago's 1933 World's Fair. Steel towers are 1825 ft. apart, connected by cables on which rocket cars carry passengers" and measures approx. 5 1/2" x 3 1/2".
