@hazofhorsham, you really make me nervous
What do you mean the "add cards"? I may open other decks to confirm this, but what are "add cards"?
Could you show me the pics?
*PS: hazofhorsham is the buyer of the last Holiday Back set.
What he meant was "ad cards", as in the extra cards in the deck used for advertising. While it's not common these days, USPC did occasionally release some of their models with less than the commonly found fifty-six in a pack (fifty-two playing cards, two jokers, and two cards with advertising). I just opened a pair of really old-looking Cincinnati Bee bridge-sized decks (I don't think they make them anymore), and the packs came with jokers but without ad cards.
It's entirely possible that USPC felt it inappropriate to include ad cards in a holiday-themed deck like that without someone taking offense to it. I couldn't begin to guess the reason it was left out of the bridge deck, other than that with a deck of such a comparatively low print run and a smaller card size, maybe no advertisers were interested.
If anyone was curious to determine the age of my decks, I have one of them on me now at work.
* Cincinnati box
* Blue sticker with a white margin turned semi-transparent from aging
* Loose cellophane; practically fell off the deck
* Old-style tuck back ("Extra Selected for Club Special")
* Long lid flap
* AoS date code is E1400, which would pin it down to either 1983 or 2003.
* White background on the tuck box has a yellow patina.
If I had to guess (and it would be a guess) I'd say it was 1983. I might even be able to get more - they were something like $3 a pack!
