Just discovered a different version of the 4th issue Cypress Bayou Casino slot card with DLR CP on the back. The originally listed card had a 12.5mm wide mag stripe and the distance from the DLR CP to the first line of text was approximately 24mm. The new found DLR CP card has an 11mm mag stripe and the text is moved slightly down making the distance from the DLR CP to the first line of text 25mm on this card.

Here's scans of the common front then the new found back and the original back followed by an overlay of the two backs so you can better see the slight difference in the text position.
