This Tuesday, Phillips de Pury & Company will be holding their more-accessible Under the Influence contemporary auction in New York. Among the lots are pieces by many of our favorite artists, including Chiho Aoshima, Marcel Dzama, Phil Frost, and Barry McGee. One notable lot is Portrait 5, Stephen(s), 2009–2010, a collaborative work by Shepard Fairey, Andres Serrano and Frank Stella, which debuted on the December 8, 2010 episode of The Colbert Report as part of an interview with Steve Martin and is now being sold to benefit school arts projects through Take a look at all our pics of pieces in the auction, after the jump.
