Quite possibly the earliest Ken Griffey Jr. home run bat ever to be made available is this signature model Louisville Slugger "B267" (30 ounces) that once belonged to Dave Valle. The young phenom used his teammate's bat to stroke a pair of dingers during his rookie season on baseball's biggest stage and afterward inscribed on it, "2 Home Runs-Yankee Stadium-5/30/89-Thanks Dave-Ken Griffey Jr." in silver sharpie (8.5/10). The impression each long ball left behind is clearly visible and adds tremendous mystique to an already Hall of Fame caliber piece.
