He was given the nickname "Boom Boom" after his father Lenny "Boom Boom" Mancini who laid the foundation for his son's career. His whirlwind punching style caught the eyes of network executives at several American television networks, and he became a regular on their sports programming. He was the reigning lightweight champion of the world throughout much of the 1980's. Mancini retired officially in 1993, leaving a record of 29-5 with 23 knockouts and a very touching and inspiring story as a brave world champion who won the title for his family, as well as for himself. Ray "Boom Boom" Mancini has hand signed this B&W 8x10 Photo vs Bobby Chacon in January 1984. Certificate of Authenticity from Athlon Sports Collectibles.
