An exterior view of the Silver Slipper Gambling Hall. A "Welcome Hunters" sign is visible above the main entrance. The Silver Slipper was a casino in Paradise, Nevada that operated from September 1950 to November 29, 1988. The building was designed by architect Martin Stern, Jr. Opened in 1950, the casino was built on the grounds of the Last Frontier Village[1] of the Hotel Last Frontier, and was originally named the Golden Slipper Saloon and Gambling Hall. The owner originally wanted to call it the Silver Slipper, but there already was an existing establishment with that name. The problem was solved when that small operation was purchased and closed, and the Golden Slipper became the Silver Slipper. The casino was known for its rotating slipper that sat atop the casino. In 2009, the Silver Slipper sign was restored and is now part of a display of vintage signs in the median along Las Vegas Boulevard North.
