The self-proclaimed “Greatest,” Muhammad Ali justified his boastful title by pummeling opponents to claim the Heavyweight crown on three separate occasions. The offered display is headlined by a cachet signed by the outspoken champion. Framed to dimensions of 13-1/4 x 16-1/2” with mauve-colored matting, the correspondence piece is postmarked “5-9-90” from Rome, Italy and signed in blue ballpoint by Ali. As powerful as his legendary punches, the signature projects (“9”) strength and clarity. Accenting the piece is a color print of Ali’s famous pose as he taunted a beaten Sonny Liston. Auction LOA from James Spence Authentications.
