ODD QUESTION, BASED ON EBAY AUCTION CONCERNING 1952 BOWMAN BASEBALL WRAPPER

Is this the only way that these cards could be purchased; if so, how could every card not have a gum stain?

ONE CENT WRAPPER

I think all of my 52 bowman cards are stained on the back, I always thought they were wax stains though.
If you're interested in buying that wrapper I can help mediate and get more information for you.

I felt like I was being yelled at while reading his description.
Thats a bummer, I just bought an ungraded set, I'll be curious to see what the backs look like, thanks for the reply.
