Really False Advertising

We all expect a little exaggeration in movie posters.  For instance, in a Star Wars poster Princess Leia is pictured in a low-cut dress that she doesn't wear on screen.  But I have discovered a case that goes too far.  I recently purchased The Wasp Woman, a Roger Corman flick from 1959.  Please examine the DVD cover art below:

So you would assume from this picture that the Wasp Woman had a wasp's body and the head of a pretty woman and was significantly larger than the average human being.  But, when you watch the actual movie, what do you see?

The Wasp Woman has a woman's body and a waspy sort of head and is the same height as she is as a human woman.
