Shelley in a spread for Avon bathing products, 1973
Shelley appeared in many ad campaigns for many different products throughout her modeling career. One of them was for Avon. Shelley appeared a spread for their 1973 product catalog called "Bathe Away The Day". It featured various Avon bath crystals, bubble bath gels, body rubs and even after-bath moisturizers and powders. Shelley, in nothing but a towel, obviously enjoyed Avon's smoothers and freshers which "made everything feel easier".
