It's an ad for Bain de Soleil (French "for sun bath"), a suntan lotion promising the type of tan all the women of St.-Tropez on the French Riviera have. The deeply tanned, exotic "Frenchwoman" in the ad is actually Kriss Ziemer, an American model. Below is a black-and-white photo showing her . . . not so tanned.
Kriss Ziemer was an enthusiastic Bain de Soleil spokeswoman, as this 1988 article from the Chicago Tribune attests, but she was hardly a foolish sunbather. She made it a point to keep her skin healthy and her tanning in moderation.
She didn't need a bronzing tan to look like a goddess. :-)
Oh yes, her agency history. Kriss Ziemer was associated with the Zoli modeling agency in New York and the Atlanta-Miami agency L'Agence before moving to Wilhelmina in the mid-eighties . . . with a brief intermezzo at the Reinhard agency in Philadelphia.
No Paris agencies, though . . .
