Only one dozen of these in existence. Hand carved image of Sandy Koufax on an official major league baseball (no two identical) and signed on the sweet spot by Sandy Koufax. Comes with coa from Steiner and Online Authentics. Koufax would not sign original art for us so we had to spend the big bucks and piggy back off Steiner and Online authentics. It mentions limited edition exclusive to World Wide Authentic on the Steiner coa.
