The advert appears to show a female model’s breasts smashing through the glass of the bus shelter, thanks to the support of her push-up bra.

The poster â€" which seems at first sight to be a victim of vandalism rather than a marketing stunt - has appeared at sites in Germany.

Last year the company scored a viral Internet hit with a risqué spoof of the cult Cadbury's drumming gorilla advert.

The Wonderbra version featured the enthusiastic and energetic musical efforts of a scantily-clad brunette whose upper-body stability was only maintained thanks to her brassière.

The advert, which had the catchline "Two cups full of joy", was never broadcast on television.

Wonderbra's other recent advertising gimmicks include painting a yellow strip in front of genuine safety lines at Singapore underground stations, to show the safe distance at which Wonderbra wearers will have to stand from the trains.
