This paper Ace's & Eight's Membership Card from Bill's Casino in Lake Tahoe is slightly different from one of the two similar card already listed in the guide. One card has 3 slot reels at the top with a smaller logo while this and another card do not. The originally listed card has the reverse upside down in reference to the front while this card has a normal rightside up reverse. There is also a slight difference in the sizes of the two cards and the radius of the rounded corners, one being larger than the other.

Here's a scan of the new found card.
