The advertisement shows a female model sporting a Wonderbra and her breasts smashing through the glass of a bus stand -- the striking poster has appeared at various sites across Germany, The Daily Telegraph reported.

The poster, published by the leading British daily, appears at first sight to be a victim of vandalism rather than a marketing stunt. It is the work of the Frankfurt branch of leading international advertising agency Publicis.

Wonderbra has had a reputation for eye-catching advertising ever since supermodel Eva Herzigov posed in the firm's lingerie next to the slogan "Hello Boys" for a campaign in the 1990s.

Last year the company scored a viral Internet hit with a risque 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 just her brassire.

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