I don't know if many people are collecting unopened promo packs or maybe some oddball packs that are hardly ever seen. I decided to start a thread about promo packs I might have seen just once or have hardly ever seen.

I used to keep some rare packs unopened but then Todd said he always opens them. It makes sense because cards can stick together over time if they get warm or if even a tiny bit of moisture gets inside. Someone once told me not to buy unopened packs of those Karl Art promos because the foil fronts have often stuck to the backs of the cards in front of them. It was better to open them when they were new.

Anyway, here's a scan of the First International Billiard 5-card promo (sample) set from 1993. I had heard of it but I didn't recall ever seeing one until last month at a flea market.
