Here's a quote from a Phil Jensen article in CCTN, but I don't know what issue (One of the "Phil's Forays" articles)...

Heading south from Las Vegas were a couple of places I could scrounge for chips. The first was Searchlight and there was a neat old place there called Sandy’s. It was originally owned by a Sandy Sandquist and the chips which bore his name were still in use. By now though, Warren Doing owned the joint and he was quite a character. One could usually find him wearing a red base­ball cap and yuking it up with the old timers who hung out in the place. Once in a while the boys would get up a poker game with some old Boulder Club chips from Vegas. They were the small crown red ones with an insert showing the old sign.

The article includes a photo, and the caption said it's probably from the early 1970's....
