At which world's fair was the Ford Mustang first publicly unveiled?

The Ford Mustang was first publicly unveiled at the 1964 New York World’s Fair.

Ford introduced the production Mustang on April 17, 1964, at the exposition in Flushing Meadows–Corona Park in Queens, New York. The event gave Ford an enormous public stage for its new compact sports-oriented car, which was designed to attract younger buyers with sporty styling, multiple body styles, and a relatively accessible price.

The Mustang’s launch was part of an unusually successful introduction. Ford dealerships began taking orders immediately, and the car quickly became a cultural phenomenon. Although officially sold as a 1965 model, the earliest cars are commonly called “1964½” Mustangs because production began months before the normal 1965 model-year changeover.

The fair is sometimes confused with the Mustang prototype’s earlier appearance. The Mustang I concept had been demonstrated at the 1962 United States Grand Prix in Watkins Glen, New York. That was not the public unveiling of the production Mustang; the production car’s landmark debut came at the 1964 New York World’s Fair.
