Back in the first run of Bill Willingham's Elementals, the character of Morningstar posed for Playboy. The character of Riptide in Liefeld's Youngblood posed for the fictional Pussicat Magazine. Given (as presented in comics) the fascination the general population has with the spandex set, I would assume that Hef, given the chance, would pursue heroes and vigilantes, possibly even villains, to pose for his magazines. I'm sure the competition would also. It would be safe to assume the lower class magazines would throw models into costumes and call it good. There might actually be magazines geared specifically towards that subject matter.
What I am looking for is possible titles to such magazines. I'm working on a story, and honestly, I'm drawing blanks, so I figured I'd turn to Herodom to see what can be come up with.
