Cartoon booklet for Kotex menstrual napkins teaching etiquette, grooming, fashion & dating to teenage girls For years copywriters for Kotex produced Are you in the know? advertisements for teenage American girls. This 1956 booklet is a compilation of these ads published by Kimberly-Clark. There are almost only Caucasians in these ads, and the advice they give, and the dress of the people, suggest at least an upper-middle class audience – but maybe that was just the times. Haven’t things changed?! The language can be hilarious and probably reflects teenage speech of the time.
