Hi Pam,
The post card you are showing is extremely rare. I purchased mine, the one I sold with my collection, years ago from Jim Gellette. Jim told me the story about the postcard. It goes as follows:
The woman on top of the Las Vegas sign was the wife of Tutor Scher (sp) who either owned or was one of the investors of the Las Vegas Club at the time the picture was taken. After the picture was taken and the postcard issued, Tutor and his wife divorced. The wife purchased as much of the run of postcards as she could so she could destroy them. Obviously, some got out........but not many.
A GREAT card, where may I ask did you get it?
Jim
