On the 1st issue cards from the Hollywood Casino in Baton Rouge, LA there is an (I) manufacturer mark and last line of text in the reverse paragraph starts with "be obtained...". On the 2nd issue cards there is no manufacturer mark and the last line of text in the reverse paragraph starts with "regulations..."

I just discovered a card with the same text on the back as the 1st issue cards but WITHOUT the (I) manufacturer mark that would have been between the original 1st and 2nd issue cards.
