From the NY Times:
Next summer, Joe DiMaggio will appear — for the first time — on a United States Postal Service-issued stamp as part of the 2012 Major League Baseball All-Star stamp series. The collection, announced on Monday, will feature three other Hall of Fame baseball players, though only Mr. DiMaggio’s name has been released.
Mr. DiMaggio’s postal debut is “long overdue,” said Stephen Kearney, manager of stamp services for the postal system. “Yankees fans are already very confident about their legacy, but this will just reinforce that,” Mr. Kearney said. “I think the biggest reaction we’ll get is, ‘What took you so long?’ ”
