Still, I learned something new. I didn't know that the cosmic marble was actually called a cosmic rainbow. Would this still be some kind of Vitro, though? I don't know if I've seen strands like this in a Marble King.
I was looking at Robert Block's "Marbles" book that said Vitro made marbles that were similar to MK rainbows. So, it sounds like their rainbow style marbles were referred to as cosmos from what I'm hearing. So would this be a Vitro cosmos marble?
Cool! I just went back to one of my books and sure enough, Vitro made a marble that was like MK rainbows. It does look kind of like an MK from some angles. This is probably what the marble is. Thanks again William.
