I know I do most of the posting in this thread, but I really hope others will post cool Yaz items as well. Here are my latest pre-1980 Yaz additions:
This checks boxes both for my Yaz collection and my 68 Venz set. This is my 5th Venz Yaz card, but my first one that's a "solo" card, without other players on it. Pretty rough, but happy to have it. Only 5 graded higher. Some paper loss on back, but not enough to obscure his face. I'm chipping away at a couple of the subsets within my 68 Venz registry. There are 7 Yaz cards in the set and I now have 3/7. And there are 10 All Star cards and I now have 3/10.
1976 MSA Red Barn disc. Everything I've read about the MSA discs (mostly in this forum) says the Red Barn one is the scarcest. PSA has only graded 7 copies of this disc. There are 2 variations: one with the Kenosha address on the back and one with no address on back. This one obviously has the Kenosha address.
