I always loved the marginalia of these ads: little messages tucked in here and there.Great mention of the Sierra Club; Earth Day was brand new when this ad ran Oct. 3, 1971. Ah, those chunky shoes with marshmallow soles. I remember it well. Shopping for shoes at Fred Braun and Bootery. Wish I still had my Huk-a-Poo sweater from that era. Leg of mutton sleeves, with tiny buttons down the front.
