Not sure
But what I am told is with candies. I have not found any references to confirm this. Surely you have seen some cars with “bands”. I believe that there was a small paper band that “bound” the card to the candy made of a more absorbent material than the card itself. Thereby the “strip” would absorb the candy and with a higher concentration of the candy material were thereby transferred to the cards. Pure conjecture, but I have a number of cards that would support this hypothesis.
