At the City Lore non-profit organization's gallery space, graffiti fans can now admire the work of two legendary subway graffiti photographers, Martha Cooper and Henry Chalfant. Entitled "Moving Murals: Henry Chalfant & Martha Cooper’s All-City Graffiti Archive," the exhibition features over 800 of Chalfant's photos of tagged trains from the 1970s and 1980s as well as portraits of the artists at work shot by Cooper.

The gallery writes of the photographers: "Chalfant and Cooper’s patience and determination in hunting down and capturing these ephemeral masterpieces with their cameras has left the world with a representative cross section of some of the best work by the most talented young artists who painted New York City’s subway cars." Chalfant spoke to Metropolis about the exhibition and added to the praise of the artists behind the tags that he photographed, saying that "What started out as what you might call vandalism, putting up a tag on a wall or a train, evolved into a real art form, and it’s an art form which has influenced an extraordinary number of people around the world."

The exhibition will run through July 10, but you're not doing anything now so you should probably check it out soon. For more information. head to the City Lore website
