Super rare ball celebrates the 1996 release of Nintendo's Ken Griffey's Winning Run video game. One full panel is covered in dark green with no printing, while the other is white with Nintendo logo on one end, game logo on the other, and Junior's autograph perfectly placed across the sweet spot. Since these were promotional items for the NES game - the second of three that the company made with Griffey, Jr's name - the ball itself is rare enough but add the autograph and this becomes a very hard to find piece. Signature is 9/10 in blue ballpoint ink, comes with JSA Authentication sticker.
