Ken Griffey Jr’s Winning Run contest prize, Propeller Arena GD-R
Ken Griffey Jr.'s Winning Run Autographed Baseball SNES
...Back in 1994 or so, Nintendo released a Ken Griffey Jr branded Baseball Game for the SNES. As part of the promotion, they had a contest, with one of the top prizes being official signed Ken Griffey Jr Baseballs.
I was lucky enough to win this contest as a kid. Now I'm ready to part with this baseball and hope it finds a happy home.
