The Queens Museum of Art let the New York Sun go behind the scenes to watch their conservator restore miniature models of the city used by Robert Moses for many of his proposed projects:
Small Models For a Towering Builder
An exhibit of these models opens at QMA later this month, along with 2 other exhibits at Columbia University's Wallach Gallery and the Museum of the City of New York.
Interestingly, this cache was recently discovered in a vault under the Triboro Bridge on Randall's Island. (Photo from NY Sun)
