The nascent Space Age, with its vista of promise, was well represented. The fair is noted as a showcase of mid-20th-century American culture and technology. In both years, children (2–12) admission cost $1.00 (equivalent to $8.34 in 2020). Admission price for adults (13 and older) was $2.00 in 1964 (equivalent to $16.69 in 2020). The fair ran for two six-month seasons, April 22 – October 18, 1964, and April 21 – October 17, 1965. The theme was symbolized by a 12-story-high, stainless-steel model of the Earth called the Unisphere, built on the foundation of the Perisphere from the 1939 World's Fair. American companies dominated the exposition as exhibitors. Hailing itself as a "universal and international" exposition, the fair's theme was "Peace Through Understanding", dedicated to "Man's Achievement on a Shrinking Globe in an Expanding Universe". However, the fair did not receive official support or approval from the Bureau of International Expositions (BIE). The immense fair covered 646 acres (2.61 km 2) on half the park, with numerous pools or fountains, and an amusement park with rides near the lake. The 1964/1965 New York World's Fair was a world's fair that held over 140 pavilions and 110 restaurants, representing 80 nations (hosted by 37), 24 US states, and over 45 corporations with the goal and result of building exhibits or attractions at Flushing Meadows–Corona Park in Queens, New York City.
