Bring "The Greatest" into your collecting fold, with this Muhammad Ali single-signed ONL/White baseball. A fairly firm ("8.5") application, Ali's blue ballpoint pen signature resides neatly on the sweet spot of this lightly toned baseball (EX-MT+). While Ali autographs are easily tracked down, singled-singed baseballs don't come around all that often, and they typically command a significant premium, when they do show up. So keep fighting 'til the finish, for this pleasing example. Auction LOA from James Spence/JSA. Opening Bid $150.
