ART FOR SCANDAL'S SAKE Some guy maybe Is celebrated graffiti artist Banksy a 34-year-old Bristol, England, native named Robin Gunningham? The Daily Mail seems to think so, though Gunningham's parents denied even having a son. Gawker agrees, and has even dug up a second photo of the purported Banksy, which indeed bears some resemblance to the only other known picture of Banksy, taken in Jamaica in 2004. But the director of the gallery that put on Bansky's first-ever show in New York City swears it's not him. "I'm not at liberty to say much, but what I can say is that Gunningham isn't Banksy," Davide Centineo, the director of the Vanina Holasek gallery in Chelsea, tells Radar.
