Is there a way to know for sure that a swizzle is from the casino? The black swizzle is from the Moulin Rouge and is very well made - very sturdy with added support on the back side. It is from Sunshine Plastics in "Hialeah, Fla" - which usually means it is older since it has the three character abbrevation for the state. I think that probably means it was from the original club (1955-1959). The one from the Roaring Twenties may or may not be from the Las Vegas club - does anyone know?
