Greg EcklundI think Adam's list is very well done, and to his I would add:
1953 Bowman (first use of color photographs)
1983 Topps Traded Darryl Strawberry/1984 Fleer Update Dwight Gooden (poster children of the early rookie card boom as well as update set mania - people would buy the whole set just to get these cards)
