I too am a huge fan of such photos. There once existed a website of a woman who called herself Trish who had ridiculously enormous fake boobs and she loved to take pictures of herself at clubs or just out in public, standing next to another woman who had large boobs, or if not large, then the woman was trying to emphasize her boobs.
the caption would always be "the battle of the boobs".
Trish always "won" the battle, btw.
The best ones were at dance clubs, because almost all of the "losers" would have incredibly jealous glares on their faces while the looked at Trish's gigantic chest.
