Twelve (12) of Michael Jordan's personally owned golf balls.  Each Maxfli Revolution golf ball is marked "23" and stamped with his initials "M.J." ensuring these were made specifically for Michael Jordan.  Half of the balls show definite use but that's not to say they weren't all used at one point.  Golf balls source from the collection of John Michael Wozniak, the security guard who gained notoriety for his famous shrug while defeating Michael Jordan during the coin toss scene in Michael Jordan's "The Last Dance" documentary, and friend of Michael Jordan.
