Here at #4 is an autograph of not only a sports icon, but a cultural icon. Muhammad Ali. This comes from the same set as the Walter Payton autograph I have which was earlier on the list. The auto, like the Payton, is on the back of the card, which of course is unusual but common throughout this set. It of course has the official certified autograph seal to ensure it's authenticity. Before Leaf started making Ali cards earlier this year, this one of the few Ali certified autographs out there. There's also a version where he signed Cassius Clay, which is harder and more expensive than this one. Nonetheless, this is an autograph I will treasure for the rest of my life, a true icon that transcended sports at a controversial time in American History. Muhammad Ali was and always will be one of the greatest of all time.
