Shelley appeared in a promo ad for the Max cigarettes' Fashion-stakes of 1976, a contest for Max customers. Max was a brand of 120mm cigarettes marketed to women (note: cigarette smoking is dangerous to your health) and was popular in the 1970s. The Fashion-stakes had as a designer wardrobe worth approximately $8,000 as prize for five lucky winners. The winners were going to be flown to New York for a stay at the exclusive Regency Hotel where they would personally select an outfit from each of the featured exciting and prominent American designers of the era - John Anthony, Stephen Burrows, Calvin Klein, Kasper for Joan Leslie and Ralph Lauren. Luxurious furs from Alixandre were also going to be given out to the lucky winners. In the promo ad, Shelley modeled an outfit by Ralph Lauren. And, as always, she looked sensational.
