An ad agency in Mozambique (!) has produced these breast cancer awareness ads featuring Wonder Woman, Catwoman, Storm and She-Hulk. It's unclear if they used these characters with the permission of Marvel and DC, but I have to imagine the companies are just going to let it slide.
As admirable as these ads are they, as is the case with many breast cancer PSAs, seem to skew towards men. They're certainly semi-titillating (sorry). I imagine most ad agencies are male-led, so that explains some of it, but as Xeni Jardin at Boing Boing (herself currently dealing with breast cancer) notes, you don't see testicular cancer ads featuring guys cupping their balls in suggestive ways.
