Hi all,
Recently picked up some 1991 Upper Deck in a trade and discovered a few of the 1991 Upper Deck sent were...defective? It's really strange. As we pulled them out of their individual penny sleeves to put with the set, several were revealed to be two pieces - a thin card stock front with white back and a thin card stock back with a white front. They were paired to appear as if a complete card when placed in the sleeve. They have the hologram intact. Not sure if this was a manufacturer defect or some kind of facsimile. Bizarre. Any ideas about the history of these?
