This is a parody of this promo art for the Avengers movie.
I couldn't help but notice that in most of the ad material, the guys are all in heroic stances but Black Widow is almost always in an impractical, curved-spine "booty shot" pose. Figured I'd flip it around for my lady friends out there. Seemed only fair.
Them's some strong male characters, amirite?
This also serves as the third and final piece of my "booty trilogy". Ya' know, as if I totally planned it or something... XD
