These latex masks are intensely, profoundly, and abjectly creepy. Here are more of them. Blank, horrid, dead things...The almost-but-not-quite human is the most monstrous thing imaginable. I think I read a study on that, long ago. Maybe something to do with unsettling imagery in horror films? Ish?

If I were making a low-budget but atmospheric science fiction or horror film, I would use masks such as these. But I wouldn't sleep well.
