Vintage Muhammad Ali Signed Red Everlast Boxing Glove, JSAFloat Like a Butterfly, Sting Like a Bee! This stunning piece features a bold, full name signature in black ink from the legendary Muhammad Ali. Early examples of Alis autograph, like this one, are highly sought after due to their elegant, full name style. Unfortunately, as Alis battle with Parkinsons disease progressed (beginning in the early 1990s), his signature began to show signs of decline, making these earlier autographs even more valuable.
