1964 Penafiel (Mexico). Soda maker. There are local players, ATGs and LA Dodgers. Here's Gehrig:
Coney island arcade Gehrig. Made by the arcade to use in International Mutoscope Reel Co card machines after IMR bit it. Ca. 1950s-1960s. I've seen two Gehrigs ever, and one Jim Thorpe
1968 Atlantic Oil winner cards. There were ten players with varying degrees of rarity. Clause Osteen ($1 winner) is the easiest--gotta be at least three of them around. Probably Wilson too. since he is also a $1 winner. I've never even seen 6 of the 10 winner cards but I've only been looking for thirty years. Here are two of them, Tommy Davis and Earl Wilson.
I would not be surprised if Davis has no other examples: he is a $100 winner.
There is also an error card that has proven incredibly elusive: Ron Swoboda with the $5 prize. He was supposed to be a common card towards a $10 prize but a handful of the cards were printed with $5 on them. Seen under five of these. Of course, it is so obscure that no one cares...
These Rodine postcards and premiums from a division of a chemical company are rare as hens' teeth too; I've seen only a handful of them:
These are PCs
This is one of the premiums mentioned on the PCs as available on request. I've seen two examples of this one
I don't even know what the other cards in the set are.
