Colts owner Jim Irsay is the manager of the famous memorabilia collection, and on Sunday he announced the addition of an autograph.
Irsay posted on Twitter that he bought the WBC championship belt from Muhammad Ali at the famous “Rumble in the Jungle” fight. The sale was made for $6.18 million, according to Sports Collectors Daily, one of the highest prices ever paid for a piece of sports memorabilia.
Ali won the belt by defeating George Foreman in Kinshasa, Zaire, on Oct. 30, 1974, and held it until he defeated Leon Spinks on February 15, 1978.
Irsay indicated that the belt will be included in upcoming shows of his memorabilia collection at Chicago’s Navy Pier (Aug. 2) and Lucas Oil Stadium in Indianapolis (Sept. 9).
The Irsay collection includes a wide variety of items from American history, pop culture and sports. He estimated his worth at more than $100 million, according to Bloomberg.
