Well, that's a thought, Primm owned the Monterey and Rainbow Clubs in California before going to Reno. I just assumed he sold before he went to Reno and bought into the Palace Club.

Maybe the Primadonna logo was used in the Rainbow or Monterey Clubs restaurant. The "menu" version must have been used somewhere prior to Reno.

I should mention that the date stamp is sharp and clear and can't be mistaken for anything else.

Thanks,

Mark
