FILE - In this April 9, 2008 file photo, Stephen Colbert is photographed at his office in New York. With help from three prominent artists, Colbert has retouched a self-portrait to please the discerning art collector eye of Steve Martin. Martin was Colbert's guest Wednesday, Dec. 8, 2010, on "The Colbert Report," where he was promoting his new novel, "An Object of Beauty." Colbert presented an old self-portrait and trotted out three unannounced guests to give their appraisal: artists Frank Stella, Shepard Fairey and Andres Serrano. (AP Photo/Jim Cooper, File)
