76 Hostess green/yellow instead of red/blue.
I got a small batch of them from a friends neighbor in maybe 1979 or 80. Traded a McCovey Washington for them, and stupidly then traded half the batch to the local dealer for another McCovey. They have every appearance of being issued on boxes. But are screened entirely differently from the regular ones, and the batch included numbers over 150.
I've never seen any others.
There was a fairly local Hostess bakery so maybe some test prints got out to the packaging line somehow. I don't think the kids family had any connection to Hostess, I'd have probably asked since I was always after the shelf ads or any other promotional stuff I could find.
The RC cola guy promised he'd send something but never did. I also met a Topps rep who claimed that he had boxes of some fairly tough stuff that he'd kept rather than put it out with retailers. (greatest moments, 74 deckle, that sort of stuff.) None was for sale since he figured it would be worth a lot more later on. I've always wondered if that stuff ever turned up.
