Here's a matchbook from The Wheel Club in Reno. TGT has it as a 1940's club, closing just after the war. No chips are shown in TCR, though. The cover does indicate they played blackjack. Do you suppose they played only for cash (or coins, more likely)? Looks like a low-end club, anyway.

Maybe that's where those pilot-wheel chips that were posted here a couple of days ago (attributed to Wagon Wheel) were used????
