Sorry for veering away from the spook theme temporarily, but I love old vinyl records and so does my son. I gave him my Elvis Album and some others when he went to college. He found this stuck in with the Elvis records and although I can remember putting it there, I have no idea what it is. It’s the size of a 33, but has a bigger center hole. It’s black like a record, but when light shines on the surface it is shiny and has rainbow colors. It also doesn’t have normal grooves. The grooves come out from the center like sun rays. Is it an old, vintage optical disc or maybe a vintage computer storage device? Anyone have a clue?? Thanks. You can click the images to make them larger.
