We already had 3 different of the paper Aces's and Eights Membership Card listed from the Bill's Casino in Lake Tahoe, NV but I just discovered another variation. Turns out besides card having the slot reels or not there is different text on the backs of all the cards. I updated the descriptions to point out the last line of text on the back that is different on each card. On this card the back is rightside up and the last line of text is "Cashier's Cage." The previously listed card like this had "Gift Shop." as the last line. Check ther ChipoGuide listings for details, the updates should be live by tomorrow.

Here's a scan of the newfound card...
