I was reading Pam's great thread of downtown Las Vegas and I had to put in my 2 cents worth. As Archie stated there are not many casinos that use multiple names on thier cards, so I consider this grouping unique.

Notice the last card in the series no longer has the Pioneer Club on it. I think that is when the Gold Strike group sold it off.

I think 5 casino names is the most I have seen on a deck of cards. Giuduci's Fun Properties in Reno/Sparks 4 Properties. And Full House, Inc. out of Elko has 4 properties listed.
