Doug: This is quite challenging, as it forces us almost to consider specific eras that center around storylines or creators we loved. In the past, the only real run I voted for was the Magneto/Savage Land epic for the All-New, All-Different X-Men. But for the most part, we've jumped around and chosen our issues from across the ages (and included Annuals, too!). The Spider-Man juggernaut that was rolling in the 70s and 80s certainly gives us a whole lot of fodder, doesn't it?
Doug: So I'm going to cop out here at the beginning, and largely defer to our readers. However, I'll picture a favorite story that introduced (to the mainstream, at least) a favorite character. And isn't this a great cover? Have fun today!
