"Doors For Doris" by artist Sam Moyer. Stone forms the foundation and framework of New York City. It is the bedrock that supports the structures we inhabit and it clads many of the too. To mark the threshold between Central Park's boulder-filled terrain and Midtown Manhattan's built environment, Sam Moyer has created a massive three-part sculpture, with a title that pays homage to Public Art Fund founder, Doris C. Freedman. Moyer's sculpture unites imported stone with rock indigenous to the New York region.
