On Monday, September 19, Sotheby’s New York held a highlights preview of the art that will be auctioned off at TWO x TWO for AIDS and Art 2011 on October 22 in Dallas, TX. The annual event is in its 13th year and is hosted by Dallas-based collectors Cindy and Howard Rachofsky at the Richard Meier-designed Rachofsky House. The art auction benefits two institutions (hence the title): the Dallas Museum of Art and amfAR, The Foundation for AIDS Research.

Around 200 guests gathered in the 10th floor galleries of Sotheby’s New York to get a first look at highlights from the auction artwork donated by: Joshua Abelow, Isabel Albrecht, Polly Apfelbaum, Hernan Bas, Justin Beal, Frank Benson, Anna Betbeze, William Betts, Steven Bindernagel, Sean Bluechel, Matthew Brannon, Sascha Braunig, Christopher Brown, James Lee Byars, Scott Calhoun, Fernando and Humberto Campana, Dan Colen, Andy Collins, Nigel Cooke, Justin Cooper, Marti Cormand, Tony Cragg, Martin Creed, Cynthia Daignault, Annabel Daou, Lynn Davis, TM Davy, Michael DeLucia, Marc Dennis, Rackstraw Downes, Leonardo Drew, Carroll Dunham, Sam Durant, Tim Eitel, Matias Faldbakken, Oana Farcas, Thomas Flechtner, Roland Flexner, Mark Flood, Brendan Fowler, Erik Frydenborg, John Gerrard, Alexander Gorlizki, Antony Gormley, Mark Grotjahn, Terry Haggerty, Tim Hailand, Robert Heinecken, Jim Hodges, Tony Horton, Ryan Humphrey, Sergej Jensen, Yael Kanarek, Matt Keegan, Alisha Kerlin, Ai Kijima, Klara Kristalova, Liz Larner, Annette Lawrence, Glenn Ligon, Liza Lou, Catherine MacMahon, Florian Maier-Aichen, Robert Mapplethorpe, Liz Markus, Cameron Martin, Nick Mauss, Keith Mayerson, Charles Mayton, Stefana McClure, Ritsue Mishima, Donald Moffett, Frank Moore, Sam Moyer, Carter Mull, Yuko Murata, Hitoshi Nomura, William J.
