Check this out! I can't believe I found this paper mache JOL at an estate sale for 2 bucks! Inside it was this metal plastic thingy (seen to the right). I thought it was a piece of trash or a broken part but I happen to stumble onto this 1957 ad for a similar one and turns out it's some sort of battery powered light doohickey!
Mine is missing his facial features but I just stuffed him with black tissue paper and all is good!
