At one time the hottest rookie card on the planet. This card is credited starting the rookie card craze. The rookie card craze now has evolved into the autograph rookie card craze but just this same. Personally, I rank the Fleer and Topps cards as better looking than this and the 1984 Donruss set as somewhat over rated (back then and today).
