Rare Muhammad Ali signed proof ticket stub from the February 6, 1967, Heavyweight Championship bout against Ernie Terrell for the WBA, WBC, NYSAC, and The Ring titles at Houston's Astrodome. Stub measures 4x2" and shows wear, particularly at the corners, and the back has discoloration that might be glue residue from scrapbook removal. Ali has signed on the front in black 7/10 marker above the image of the Dome. Emotions were high after a spirited pre-fight argument between the two, prompting some to accuse Ali of extending the bout to an easy unanimous decision to inflict more damage on Terrell. The Greatest himself admitted that this was not the case and he was surprised by the resilience his opponent had shown to stay on his feet for the full 15 rounds.
