Love the 25-pound Playboy Club London chip -- a modern classic.

Marilyn intersected our historical chip locations when filming "The Misfits" in Reno. A few scenes inside Harrah's Reno in the film. And it appears they stayed at the Mapes. See:

I thought the movie included Harold's Club too, but maybe just Harrah's.

All 3 (Harrah's Harold's Club, Mapes) are closed & gone now.
