Oh, Marvel. Come on. You know better than this —this being Milo Manara's cover for the upcoming Spider-Woman #1. If you're wondering what the hell Jessica Drew, a.k.a. Spider-Woman is doing, I believe it's what's known in the animal kingdom as "presenting."
Here's the full cover in all its opposite-of-majesty:
First of all, even the dumbest, horniest teenage boy on the planet knows there's no fabric on this earth that could possibly cling to Jessica Drew's individual buttocks like that. She looks like she's wearing body-paint, and that's a big no-no for an industry still trying to remember that women exist and may perhaps read comics and also don't want to feel completely gross when they do so. As for the position she's in... christ. It's like you want The Hawkeye Initiative to get so furious they have brain aneurysms and die.
Of course, sexy comic art has its place, and Manara is quite good at it. But perhaps asking an erotic artist to draw one of your most popular superheroines for a mass-market cover wasn't quite a good idea. Also a bad idea: Receiving this cover and pretending like you didn't notice Spider-Woman sticking her bare red ass three feet into the air. Here's a simple rule: If it's inappropriate for a male character, it should also be inappropriate for a female character.
