Okay. I know these old tweakers in North Hollywood, and they like to do shit like glueing Barbie heads onto Hot Wheels. So though I DON'T know what it is, I'm pretty sure I know where it came from.
Oh shit!
I remember having the faces to play with as a kid. I always wondered what the point of those rubbery death masks was. We'd just put them on our fingers and chase each other around with them. They had the most toxic oily rubber smell you could imagine.
Yeah we also had a couple of those faces... Which begs the question: was this contraption made afterwards to use the faces, or was there just such a huge surplus of faces they had to sell them as individual toys?
Thanks to a link on John Hodgman's Twitter page I found that this thing is called the Magic Monster. There are some pictures of it on Flickr in the "Toys That Shouldn't Exsist But Do" picture set. Right underneath the God Jesus toy robot.
