Hey all, thanks for looking.

I rec'd. my KEMS (along w/ chips and case) from 5star an hour ago, and when I was looking at the cards, I noticed on one of the two jokers, in each deck, has a letter written on the chest, it actually looks like pencil, or maybe pen. I have never heard of this. Is it normal? Any one else see this before? Here is a picture.

Jokers! Is that a J and an E hand written on my KEM JOKERS?????
