231 East 47th Street, later the site of Andy Warhol's first "Factory," September 23, 1947.

In 1963, as his Pop Art works began to gain traction, Andy Warhol rented a large studio space on 47th Street for an annual rent of $100. Sometimes described as the "Silver Factory" for its tin foil and paint decor, Warhol's fourth floor loft became a fashionable performance space, production studio, and party venue for the artist and his acolytes, known as the Warhol superstars. The Factory moved to a new downtown space in 1968, with the "Silver Factory" building slated for demolition.
