Since I just posted a Wilt Chamberlain signed 8 x 10 it’s only fitting that I post biggest rival, Bill Russell. Bill Russell is a dominant force for the Celtics both offensively and defensive. He won 11 NBA championships with the Celtics and will always be remembered as one of the greatest Celtics, and greatest men, to ever play the game. This is a beautiful black-and-white 8 x 10 with His autograph in blue sharpie, clean. Bold. And bright.
