The MFA Design's first year exhibition is under construction. Its not easy getting twenty ex-presidents together in two rooms. But Kevin O'Callaghan's class is busily building campaign headquarters for Washington, Lincoln, Clinton, Bush and 16 more former heads of state who are running for reelection in 2012. The audience will have a chance to vote on their favorite POTUS. Stay tuned for the opening on May 7 at the SVA Gallery, 209 East 23rd Street.
