Last week we told you about the 15 sexiest 3D magazine pictorials in recent memory, including Anna Kournikova's stereoscopic spread Maxim's October 2010 issue. This week we want you to feast your eyes on London's first 3D outdoor billboard, which features Brazilian smoke show Sabraine Banado modeling for Wonder Bra outside London's bustling Waterloo train station. Now both London pedestrians and Waterloo's 80 million-some passengers a year can gawk at the busty optical illusion through a pair of 3D boob goggles while waiting for a train. According to Copy Ranter, the advertisement is a gimmicky stunt for the Full Effect WonderBra, a push-up brassiere purposefully designed to make women's jugs appear two sizes larger. We'd like to shake the hand of the hardworking engineer and cleavage connoisseur who decided to push human ingenuity one step further by designing this boobalicious modern model. Unfortunately, we doubt "3-DD" billboards wih plump, succulent mammary glands will be making their way to United States anytime soon. Get on it, Madison Avenue! two more photos after the jump.

And finally, via The Sun UK, here's a minature version of the billboard:
