Yeah, I think it's a challenge to figure out what to take away from it. DID Pink or Sellers know something about those handmade marbles we don't know? Or did they maybe not understand how the handmades were made?
And what about those "first American glass marbles"?
Also we've discussed that line of weird "cat's eyes" before - at length in at least one past thread - after which I think people walked away without feeling there were answers. But someone mentioned they might actually be what were called cat's eyes back then, maybe the ones Vacor made in the 1940's. So there might be more good info in the article than I at first imagined. Just gotta pick it out. . . . . Edit: Someone had actually attributed the Vacor claim to Cathy Runyan, but I just emailed her about it and she said no, those weren't the Vacors she saw at the factory. Darn it, I thought I had figured those out.
