If you've never had a chance to see the Panorama firsthand, then you should drop what you're doing and head out to Flushing Meadows-Corona Park this instant. (Unless it means you'll get fired from your job, in that case you can wait until this weekend.)
The Panorama is a 1:1200 scale model of the city of New York, where one inch is equal to 100 feet. Conceived by Robert Moses for the 1964 World's Fair as a showcase for the city's municipal infrastructure (in other words, the Moses vision for the city), it took over 100 people from the architectural model makes Robert Lester & Associates to build.
In 1992, Lester & Associates were again employed to conduct a renovation of the entire Panorama, which might be what this photo is celebrating.
But we're not sure, and while we recognize some of the people in the photo, there's some that we're not sure of. If you can put some names to the faces or have an idea why they are standing on one of the centerpieces of the Queens Museum collection, drop us a line at firstname.lastname@example.org.
