When measuring a pugilist's impact on the history of the sport, the description best pound-for-pound fighter is often evoked. When it comes time to debate Mike Tyson's skill level and place in the history of boxing, that term is irrelevant. In a career that spanned 58 professional fights, the Brooklyn native won 50 of those contests and notched a remarkable 44 knockouts. That equates to 88 percent of Iron Mike's victories coming via knockout. He was and continues to be one of the most feared boxers ever to step into the ring because his mighty jabs and powerful uppercuts could knock a guy out within seconds. He won his first 19 pro fights with a knockout, including 12 in the first round. His hands inside a pair of boxing gloves were as lethal of weapon as there has ever been in the sport of boxing. Tyson has signed this pair of red Everlast boxing gloves in black paint pen. His signature is deemed authentic by virtue of Upper Deck Authenticated's Five-Step Process.
