This is a 8x10 personally autographed by Bill Walton and as you can see he added ""NCAA POY 72,73,74"". Arguably the greatest college player of all time he led the Bruins to a 88 game win streak and two national championships. He was drafted with the first overall pick in the 1974 draft by the Portland Trailblazer and quickly led them to a NBA championship in 1977. He won another championship with the Celtics in 1986 just one year before retiring. This was signed at the Mounted Memories show in Chicago IL on March 24, 2013 and includes a James Spence matching serial numbered hologram and certificate of authenticity.
