The seller only has 4 ebay sells and the other stuff being sold isn't cards, so that is odd because they don't appear to be some major vintage card seller. I would assume they are really shocked. There were three main bidders. If it was something rare in the lot, it was not obvious based on the header, so I would think serious collectors would have a challenge even finding it in all the ebay chaff. Maybe someone saw it and posted or communicated to other interested collectors. Still, it is odd. I am also not very knoweledgable on vintage cards either. It just seems odd. The high bidder only has feedback on 13 items. The second and third highest bidder have several hundred items with feedback...It is a mystery to me. Thanks for sharing though. I will be interested if someone can shed some light on this lot.
