Henry Chalfant, AKA Henroc, was a sculptor when he first moved to New York City back in the early 1970s. As an artist, he was able to appreciate the wild colors and drips he saw on the sides and insides of subway cars. Actually, he became obsessed with graffiti, so he began to take photographs and document the art movement that literally moved. His photography would help to define and inspire multiple generations via the book Subway Art (which he co-produced with photographer Martha Cooper). Chalfant’s photographs offer sneak-peaks of people, places and things that few were privileged enough to view. Now, you can consider yourself one of the chosen few. Here are Chalfant’s from Mass Appeal Issue #52.
