IT'S STRANGE how often adult collectors of comic books are stereotyped as childish, geeky or – at best – eccentric. In fact, not only is it odd, but in most cases, it's just plain wrong. Sure, back in the day, most superhero comics were cover-to-cover campy fun, written and marketed for an audience of 'tweens. But during the Reagan era, mainstream comic books left "camp" where it belonged – following "summer." Writers, artists and publishers decided to get serious on fans. And pop culture noticed. Lately comics have been as much a part of the Hollywood universe as they are the Marvel and DC universes, banking hundreds of millions of dollars from PG-13 and R-rated movie adaptations.
