NOW I'm going with the dates in Mr. Leis' post above! The box I have with my cards looks the same as yours but matches the color of the back of the decks. BTW, where all do you think your Aunt dealt? Nevada Club? Don't be shy about passing along a story or two if you wish!

The cards I have are unused but that is one of the peculiarities of Lincoln Fitzgerald's properties. Plenty of items from chips to cards to anything else would get stored away in warehouses around Reno to be discovered years later. These hoards have been found a couple of times, one last year, so new Nevada Club stuff is available but doesn't compare to the connection you have with your cards!
