This is a rare piece of Nevada history. A thick paper coaster from "The Gayest Spot on U.S. Hwy 95", El Rey Club in Searchlight, Nevada.
Willie Martello, known as "The King of Prostitution", operated a resort/casino/brothel called the El Rey Club. The resort was open from 1946 to the late 1950's when the club burned to the ground. I believe this coaster dates to the mid-1950's.
