Wow some amazing cards. I've recently become interested in vintage Kems and was hoping someone might have an answer to this question.
After a new set of Kem cards I bought degraded to an unusable condition after 3 months, simply sitting in their case under my coffee table in an Australian summer I started looking for older ones from the original company. I bought a nice 845 bridge size double set in the upright, presumably Bakelite, case and an unopened poker size 1082 deck in the soft plastic case. My question is when did Kem start making poker size cards and were they ever made back in the Bakelite day as the very old decks all seem to be bridge size.
Yeah, plastic and heat don't get along together... Always store in a cool, dry place!
Have you tried washing them? It might revive them, assuming they didn't just turn into a puddle in the box.
That is a great question, to which I do not have an answer. What I believe is the earliest KEM poker size deck that I have has a very strange date code on the Ace of Spades: K125116 It is also the only deck I have seen with a regular style tuck box. From the style of the tuck box I'd guess 1970s. My other poker size KEMs are from 1986 and 1987 in the single vinyl cases.
There is a reference to a "Poker" deck in a 1940 catalog, but I've never actually seen one, and I don't know if it was poker sized.
That is a kick-ass find! I've never seen Kems in a paper box like that. I would even wager to guess, based on the box design, that it could even be from circa 1960s. Is there any ZIP codes mentioned anywhere on the cards or the tuck? That would definitely date it to 1965 or later. Without ZIP codes, it's more likely (though still not a guarantee) that they were pre-1965.
I believe the one labeled as a "Poker" deck actually says Poker on the card back and is the name of the deck. In all cases I have seen Kem list their poker-sized cards as "Wide" and not "poker-sized". Here is the one that I have that is named "Poker", which, ironically, is bridge-sized.
As for Wide size, I have never seen anything earlier than the ones that arrive in the vinyl cases.
It is very ironic, but less so these days. More poker players (and casinos) use plastic decks in bridge size than poker size, since the popularity of Texas Hold 'Em exploded. It's easier to hide the narrow cards under your hand when peeking at the indices from the table.
