The best-known permanent exhibition at the Queens Museum is the "Panorama of the City of New York", which was commissioned by Robert Moses for the 1964 World’s Fair. A celebration of the City’s municipal infrastructure, this architectural model includes every single building constructed before 1992 in all five boroughs, at a scale of 1 inch = 100 feet (1:1200). The "Panorama" was built by a team of 100 people working for the architectural model makers Raymond Lester Associates in the three years before the opening of the 1964 World’s Fair. The model was constructed in 273 sections, depicting a total of 895,000 individual structures; the section showing the Far Rockaway neighborhood was never installed, due to space limitations.
