The Larry Holmes Collection, a remarkable trove of his boxing memorabilia, will be sold as part of Grey Flannel's Summer Games auction on June 5.
The collection features an array of items spanning Holmes' outstanding career, with his 1978 and 1982 WBC Heavyweight World Championship belts standing as the most valuable lots, each starting at $2,500.
Holmes turned professional in 1973, working as a sparring partner for the likes of Muhammad Ali, Joe Frazier and Earnie Shavers. He won his first 48 professional bouts, falling one short of matching Rocky Marciano's record of 49-0.
His first WBC Heavyweight Championship fight came in 1978, which Holmes won against Ken Norton in the 14th round.
He held onto his WBC title until 1983, when he relinquished the belt to accept the World Heavyweight Champion title of the newly-formed International Boxing Federation.
His left jab is considered one of the finest boxing has ever seen.
For collectors of boxing memorabilia, Paul Fraser Collectibles is currently offering this signed photograph of vintage heavyweight James J Jeffries, aka The Boilermaker.
We also have a fantastic signed image of Muhammad Ali on his historic meeting with The Beatles.
Also featuring in Grey Flannel's sale is another collection of career memorabilia, this time from basketball's "Pistol" Pete Maravich. Starring is his Hall of Fame induction ring, which holds a minimum bid of $10,000.
Pistol Pete played for the New Orleans (now Utah) Jazz, as well as the Atlanta Hawks, from 1970-1980. Described as "perhaps the greatest creative offensive talent in history", his career was cut short when injuries forced his retirement.
Nonetheless, he remains a highly respected player, with Hall of Famer John Havlicek commenting in a 2010 interview: "the best ball-handler of all time was Maravich."
