I can't remember my first comic, though "Avengers" #221 was an early favorite, but I do remember finding out that such a thing as a "comic book shop" existed right around my 14th birthday. That was just about the time "Watchmen" was coming out, though I only ended up getting the even-numbered issues at first, for some bizarre reason.
My learning curve, and exposure to great comics was steep, going from "Web of Spider-Man" and "DC Comics Presents" to "Dark Knight Returns" and "American Flagg!" and "Marshal Law" pretty quickly. I was deeply in love with the medium, and I haven't stopped buying comics every week since. Now I get to write books, articles, essays, and columns about them. Not too bad. Not too bad at all.
