Why didn't someone stop this & say "Wait, we have a serious problem here."

This poster was released in the mid 80s and prompted a total recall of all posters because of the picture painted in ice-cubes at bottom right corner - a woman performing an act. The graphic artist who designed the picture put this in as a joke, and it went through unnoticed until someone spotted it on the back of a Coke truck. The artist lost his job and was sued, and all promotional material had to be recalled and destroyed. Very rare and hard to get hold of — released in South Australia in mid '80s.
