When the Eldorado Resorts acquired the Isle of Capri casinos they continued using the Fan Club slot cards but changed the text on the back and they now say Copyright Eldorado Resorts Inc. The current cards are copyright 2018 with no manufacturer's mark so they have a common back as shown in the scans below.

Note that the Eldorado Resorts also has a series of One Club slot cards used at a number of their casinos (Eldorado Reno, Eldorado Shreveport, Silver Legacy, Circus Circus Reno, Scioto Downs, Mountaineer, Isle Bettendorf, Isle Waterloo and Isle Westlake) plus they have the Grand Victoria Casino in Elgin, IL that has it's own slot card and the Montbleau, Belle Baton Rouge, Lumiere and Tropicana Atlantic City, Evansville and Laughlin all continue to use the TROP Advantage cards although now under Eldorado Resorts. Should be interesting to see how long they continue using all these different slot cards.
