I just listed this matchbook on ebay as well. It shows the historic Trocadero Lounge and the Hotel El Cortez in Reno, probably during the 1940s. You can compare it to the postcard from the same location. The postcard is postmarked 1950. The El Cortez has been there forever, but I know the chips are few and far between. I love the art deco look. I don't collect matches, so I've just put it on ebay; you can follow the link below to my ebay auctions. I've also just listed Shamrock matchbook in the scan.
