In the 1940's, Salvador Dali painted this masterful poster for the armed forces to warn soldiers against the dangers of fornicating with loose foreign hussies and contracting veneral disease. The composition of the sickly green skull from the pert-breasted prostitutes is just breathtaking, especially the way their milky upper thighs, exposed above garters, form the front teeth.
