During his Hall of Fame college and professional careers, Bill Walton's lanky build and long arms made him look even bigger than his impressive 6'11" stature. Almost as big (figuratively, of course), is the icon's signature in 9/10 silver Sharpie paint pen on an official Spalding NBA basketball. The ball itself is in NM-MT condition making for a stellar presentation of the man who was named to both the NBA's 50th and 75th Anniversary All-Time teams.
