This pink plastic swizzle is marked "Lei Vapors Hot Springs". There is a Hot Springs, Arkansas that had a notorious establishment called The Vapors which was a nightclub during the last era of illegal gambling in the city. Upscale entertainment in the style of Las Vegas, Nevada—featuring well-known acts like Edgar Bergen, the Smothers Brothers, and Tony Bennett—distinguished it from many of the rival clubs in the area. However, it's not clear if this swizzle was from there or another similarly named establishment.
