Johnson's card is No. 647 in the 1989 Topps set, and this one is Near-Mint to Mint condition and comes with a one-screw holder for protection. You can buy his Score rookie card of the same year -- or bid at the MLB.com Auction on a slew of Big Unit cards including rookies from Upper Deck, Donruss and Fleer.

Mariners Personalized Home Jersey. How good was Johnson? In 1995, he went 18-2 with 294 strikeouts to just 65 walks, on the way to his first Cy Young Award.

Customize one with his name and number for old time's sake and again try to get his signature before the five-year wait puts him in Cooperstown.
