Photos from the Queens Museum (the scale 3D NYC Panorama and NYC water supply topography) and some more of the Unisphere.
The Panorama is quite cool. It gives a good sense of how big the city really is. It was built in 1964 and last updated in 1992. More info here: http://www.queensmuseum.org/exhibitions/2013/10/30/panorama-of-the-city-of-new-york/
