Card Identification Forum

Hello everyone.....recently I was putting my '95 Bowman baseball in pages and noticed 4 of the cards have blank backs.  I did not know blank backs were associated with these cards.  Maybe promo cards?  Would appreciate if anyone has more info on these blank backs. Not much good to upload any pictures as the backs are completey white.

Thanks

Printing errors. Some people collect them, but they don't get listed here.

Also sometimes the wax boxes might have pics of the cards, and they get cut out. That's another way blank backs can show up.
