Dwain;
In general you can say that, but some special cards are made ocasionally for a given location, like the Harrah's/Rincon grand opening cards with a picture of the casino. Also the multi-property cards change design often and the newest cards are not always being used everyplace. Also special cards are issued from time to time and they may not be available at the same time at every caino such as the Elvis and Race Car cards.
