Shelley appeared in a 1978 Spanish language ad for a contest organized by Charlie Perfume. The contest, held in Mexico from June 15 to July 31 of that year, was open to all young, cheerful, adventurous, stylish and open-minded girls who wanted to be a Chica Charlie, a Charlie Girl. The winner got $50,000 in cash, a wardrobe worth $40,000 and $10,000 worth of Revlon products - all adding up to $100,000. By then, the Charlie brand was so successful, it was a household name, and Shelley's image had become synonymous to the Charlie brand. And as you can see, by the mid-70s, "El mundo es de Charlie" - the world truly belonged to Charlie.
