Coca Cola advertised in Australia with this poster, somewhere during the eighties. Until someone discovered what could be seen in the ice cube on the right ... That's not a bottle she's going to put in her mouth ! The artist, which probably thought it was a good joke (it was), was fired and sued. All posters were recalled and a new campaign was launched.

This ad appeared in the British Yellow Pages The title is of course already double in itself. But if you turn the picture upside down and cover part of it, you can see a young girl fingering herself. I think this is the most convincing example of a subliminal ad, possibly also a joke. What else would the picture of a drinking woman be doing on an ad for flooring ?
