Recently Upper Deck celebrated Michael Jordan’s 50th by having a special birthday card for the basketball legend. As Upper Deck’s longest tenured spokesman Michael takes time out a few times a year for signing sessions exclusively for Upper Deck for trading cards and Upper Deck Authenticated memorabilia. We caught up with Michael last week where he was signing cards for 2012-13 SP Authentic Basketball. This image of Michael signing the Letterman cards was too good not to share. Enjoy!
