Here's a dozen 30-strike covers from a few lesser-known establishments from fabulous Las Vegas. These may not old or rare, but most are from small/short-lived joints (i.e. lower quantities of matchbooks made) vs. the big-time casinos that made tens of thousands of matchbooks, making these IMHO very desirable and harder to find.
Enjoy!!
