The listing, PROMOTIONAL Unusual ROUND DECK of PLAYING CARDS Still SEALED has ended.
Up for bid is a sealed deck of round novelty playing cards. This is a new and unused promotional item.
Cards were produced for Pharmacia & Upjohn Company. This company gives out training and educational manuals for proper animal health protocol, and the treatment of livestock diseases.
0% MILK DISCARD 100% PEACE OF MIND is one of the company's trademarks. These were probably distributed by salesmen to dairy farmers.
I've scanned the front and back. If you collect novelty decks of cards, or just want a deck that is a conversation piece to use with your card-playing friends, this one certainly meets that criteria!
Smoke-free home.
