For W, she painted Michelle and Sasha Obama in the audience at the democratic convention as Barack Obama accepted the presidential nomination. “Live Forever: Elizabeth Peyton,” a retrospective, runs through January 11, 2009, at The New Museum of Contemporary Art in New York. it travels to the walker art center in minneapolis, the whitechapel gallery in london, and the bonnefantenmuseum in maastricht, the netherlands.
