Sept. 28, 1976 Muhammad Ali vs. Ken Norton Yankee Stadium Heavyweight Championship Full Ringside Fight Ticket.  The ticket has been signed by both Ali and Norton on the front and back of the ticket.  The autographs have been authenticated by PSA/DNA and come with a Letter of Authenticity from them.  The ticket is in excellent condition in its full state with bold autographs of both fighters.  The bout was the last of the Ali vs. Norton trilogy and its result, an Ali win via unanimous decision, is often disputed by boxing pundits.  In retrospect, Norton landed more punches, had a higher accuracy of landed punches, and delivered more power punches in the contest.
