Here's a photo I just found of Harrah's Thrifty Gambler (formerly Harrah's Club), along the California state line next to Harvey's Resort Hotel, in September 1968.

Across Highway 50 at Harrah's Tahoe, Bobbie Gentry is on the marquee of Harrah's South Shore Room. (A year later, Bobbie Gentry would marry casino owner Bill Harrah.)
