In a similar ad, we now see how modern mothers of the 50s and 60s handled this delicate subject with their daughters.
Kind of rude I admit but that ad had nothing on the ad below that kind of illustrates what our 50s era modern mother was eluding to. Subtle like a brick to the side of the face. Yet another example of an ad designed and written by a man, sold by a man and bought by a man. Keep in mind - these are both real ads from back in the day.
