The Space Age was on display at the 1964 World's Fair in New York, which opened 50 years ago. Visitors could see a movie about Moon (top left), a Mercury capsule (bottom left), a Titan rocket and Gemini spacecraft (top right), and concepts about lunar bases (bottom right), among many other space-themed attractions. At center, the grand symbol of the fair was the Unisphere, a stainless steel sphere encircled by rings representing the orbits of early spacecraft. The fair ran for two years, drawing more than 50 million visitors.
