Perhaps the most anticipated prize fight in boxing history, the March 8, 1971 meeting of undefeated Heavyweights Frazier and Ali was the first of the historic trilogy, and likewise Ali's first professional defeat. This original poster for the television broadcast of the bout is autographed by the victor and the vanquished, the latter adding "AKA Cassius Clay" to his "Muhammad Ali" signature. Both autographs rate a perfect 10/10, and the 14" x 22" card stock poster exhibits no flaws worthy of note. Accompanied by a full Letter of Authenticity from James Spence Authentication (JSA).
