There are quite a number of Casino's in the STATION CASINO's Group. Each of their Poker Rooms have given out Card Guard's in their Poker Rooms at various times. I believe that the you have were for a Promotion. However, I do NOT think that the November 2007 was ever used although a number of them have found there way into general circulation. Take a look at www.cardguardgallery.com and follow these easy directions:
1. Go to the HOME PAGE of www.cardguardgallery.com
2. In the Filter the Card Guards by panel, type station into the Title/Keyword Box
3. 'Hit' the Submit Button

These will be of interest to Card Guard collector's.
I hope that this helps.
