Who was the young girl who appeared in the Coppertone ads?

In 1959, a 3-year-old girl in pig-tails named Cheri Brand posed for a family snapshot in the backyard of her Bronxville, NY home and soon became Little Miss Coppertone®, a symbol of summer and poster-girl for the long-running Coppertone sunscreen ad campaign whose famous slogans proclaim "Don't be a Paleface!" and "Tan - Don't Burn."

The Coppertone ad campaign was based on drawings created by Cheri's mother, Joyce Ballantyne Brand, a commercial artist (who also drew the Pampers baby in 1977).

She was paid $ 2,500 for the artwork based on her little girl. Cheri Brand once said "Everybody has their baby pictures in their family album with their diapers falling off, I just happened to have mine on a billboard" (and a few million bottles of suntan lotion).
