The 1964/1965 New York World's Fair was the third major world's fair to be held in New York City. Hailing itself as an "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"; American companies dominated the exposition as exhibitors. The theme was symbolized by a 12-story high, stainless-steel model of the earth called the Unisphere. The fair ran for two six-month seasons, April 22 – October 18, 1964 and April 21 – October 17, 1965. Admission price for adults (13 and older) was $2 in 1964 but $2.50 in 1965, and $1 for children (2–12) both years .
