On May 21, 1966, Muhammad Ali made the fifth defense of his heavyweight title against Henry Cooper in a rematch of their famous 1963 non-title bout, this time with the championship on the line at Arsenal Stadium (Highbury) in London before a massive British crowd eager to see their countryman challenge the brash American champion. Ali stopped Cooper on cuts in the sixth round, continuing his reign as one of the most dominant heavyweight champions in boxing history during this early, pre-exile phase of his career. Offered here is a full, complete ticket to this historic championship bout, promoted by Harry Levene, documenting a Ringside seat priced at £10-10-0, Block J, Row U, Seat 87, with the full four-panel ticket intact including stub and information panels detailing stadium access and event rules. Graded PSA EX-MT 6, this ticket represents a well-preserved survivor from a signature Ali title defense fought on foreign soil against a beloved hometown opponent. A compelling piece for any Muhammad Ali or boxing history collection.
