The 1st issue red R Card slot cards from the Resorts Casino in Tunica, MS had two variations where the insert arrow had a black shadow around it on one version and NO shadow on the other, both with the Innovative manufacturer mark. The Resorts Casino in East Chicago, IN had a similar card but we only had one variation listed there, a card WITH the insert arrow shadow. Well I just discovered the East Chicago card WITHOUT the insert arrow shadow so it's been added to the guides.

Here's scans of the front of the new and old variations from the Resorts East Chicago Casino
