You might try Bill Judge -- he sells vintage photos on ebay. A recent post from him:

Also, Pam G. might have something. She posts here with a wide variety of pics and stuff.

FYI, it was located at the intersection of Sahara & LV Strip, where the Bonanza gift shop complex now operates.

Good luck finding ...
