1 - Iconic cover, #1 issue.
3 - Introduces either villain 1 or 1A for Spidey.
2 - Great cover, iconic villain, hard book to find in presentable shape due to red cover
4 - Another iconic villain's 1st. For whatever reason, my favorite early cover.
6 - Iconic villain's first, dropped because cover (to me) is dull.
9 - Great villain, great cover
10 - Eh cover, Enforcers irrelevant now, but were big deal for first 40 issues or so
7 - Second vulture...did we really need to see him again so soon? :-P
8 - Bumped because of the first Spidey - Torch interaction. issue otherwise.
5 - Way too early in a title's run for a filler issue. Such is life.
