William B. Tubby, 1894-96. Once a wool exchange, home to the American Thread Company, and an exhibition space where Keith Haring painted a (recently rediscovered) mural...all this history pales next to the incandescent fact that Naomi Campbell once lived here.
I say a little bit more about the American Thread Building on my New York City landmarks blog, The Masterpiece Next Door. It's a little light on Naomi Campbell, though.
