MONTAUK-based fashion photographer Raphael Mazzucco says he was stunned when British artist Damien Hirst bought the whole collection of his work on display during Art Basel for about $750,000. Mazzucco said Hirst bought 15 pieces of his artwork displayed at Mr. Chow in Miami Beach during a party for his book “Culo,” which features artistic shots of delectable derrieres. Mazzucco told us, “Damien bought the entire collection, which I could not be happier about. He is really one of my favorite artists.” Hirst held court at the party Friday night along with Naomi Campbell, Sean “Diddy” Combs, Will Smith, Adrien Brody and Chris Bosh.
