Here is a 1960 Freedomland U.S.A., Hallmark pre-opening postcard, from the short lived Bronx, New York amusement park depicting an artist rendering view of the world's largest entertainment center in the shape of the United States. (I believe that this is a little exaggerated - Yah Think!)
Freedomland was conceived by Cornelius Vanderbilt Wood who had previously worked in the planning, construction, and management of Disneyland. Hired by Walt Disney in 1953, Wood was the person who selected the orange grove site in Anaheim, California, where Disneyland was eventually built. (This is according to Wikipedia ???)
Freedomland U.S.A. opened on June 19, 1960 and closed in 1964. This is one of my favorite postcards of a place that I have never been to.
