It may be monotonous, but I chose another issue from my earliest years of collecting. It's the first part of the Kraven's Last Hunt/Fearful Symmetry storyline. Like some of my other choices, this is one that was probably a little scary for me that age. Someone cases Spider-Man and actually shoots him (I don't think it was clear at that point that he was tranquilized). Coming from the stable world of episodic super-hero cartoons, this was shocking. I know that echoing my comments on Transformers #5, but this was another case of comics going beyond the limits of the expectations that television created for episodic storytelling.
Reading your entry, I realized I messed up my own history of Spider-Man reading. I mentioned seeing Spider-Man in Transformers and Avengers before starting to follow his adventures regularly in Amazing Spider-Man #362.
But I think in Summer of 1990, my family and I went to stay at a cabin along the Russian River and my father had brought me a grab bag of comics for the trip. It included the Thor annual that made the climactic chapter to Atlantis Attacks, which had a guide to cosmic deities as a bonus feature, and Web of Spider-Man #31-32. I was too young to really appreciate these comics, I think. I remember my mother asking what happened between part 1 and part 4, if he was buried in part 1 and crawled out of the grave in part 4. I suspect I was also confused as to where parts 2 and 3 might be.
It would be several years before I would get the rest of Kraven's Last Hunt and read and appreciate it.
