Shaquille O’Neal is curating his first art show, charmingly titled “Size DOES Matter.” The 7-foot-1 Cleveland Cavalier is putting together the show featuring large pieces of contemporary art, including works by Maurizio Cattelan, Andreas Gursky and Ron Mueck‘ssculpture of a naked, hairless giant called “Untitled (Big Man.)” Talking about whoppers, author James Frey — whose memoir “A Million Little Pieces” was found to contain a few tall tales — is writing an essay for the exhibition catalog. The show opens at the Flag Art Foundation on West 25th Street in February. Shaq told Bloomberg News curating was like playing basketball: “I have a responsibility to the artists, who are my ‘teammates.’ We all have to make each other look good — no different than what I do on the court.”
