Rare 1991 Acorn Biosphere Promo Cards

CompleteBLUE BACK VARIATION SET
CompleteREGULAR GREEN BACK SET

Back in 1991,mostly on Long Island,NY, theregular green back cards were giveawaysto promote the Biosphere Base Set Product which was never produced. Once in a "Blue Moon" someone would obtain a Blue Back Card. I am very aware that these Blue Backs are so rare that even the most seasoned Non-Sport Promo collector/dealer may not know they exist! That makes for a tough sell so please feel free to message me with any questions you may have.
