Thicker head gaskets/ less compression...

Yup. That's her. The argument rages as to whether it's photoshopped. I think it could go either way. I have a big copy too and all the shadows are right. If it's fake, it's a goodun. They did a show called Munsters After Dark in the UK that was more risqué. That is one theory as to where the pic came from. Who knows? She was a hottie either way.
