If you search a bit on the web you can find collections of hand-colored vintage postcards of performers from the Casino de Paris.  These ladies were the forerunners of the Vegas
showgirl by a line of direct transmission — the legendary topless revues in Vegas were staged by artists who’d worked at places like the Casino de Paris.

Donn Arden, for example, who created Jubilee! more than twenty years ago, once worked for the Cafe Lido in Paris, home of the famous Bluebell girls and one
of the classic French topless revues.  Jubilee! is the last of the traditional showgirl revues still surviving on the Vegas Strip.
