U.S. President Barack Obama speaks in front of a statue of former U.S. President Abraham Lincoln in the Oval Office of the White House in Washington, in this January 29, 2009 file photo. Obama's reverence for Lincoln and the 200th anniversary of his birth have thrust the 16th U.S. President into the limelight as the subject of a new exhibit and upcoming auction in New York.
