Just discovered there are actually two different versions of the black Owl Club Casino Rewards card from the Hooter's & Owl Club Casino in Spokane, WA. The difference is the size of the QRcode on the back of the card. On the originally listed card, the QRcode is 26mm square in size. The newly found card has a 24mm square QRcode.
Here's scans of the common front then the 1st and 2nd issue cards.
