PWK - Pre-"The Feminine Mystique"
From the Pine Bluff Commercial, Wed, April 12, 1961. I love the use of Barbie to help explain the oh-so complicated positioning issue to the fairer sex.
My favorite quote in the article: "He (PWK) warned against the temptation of getting too close to one speaker, commenting, 'If you stuck your head in a tuba, you wouldn't expect to hear the whole orchestra!'"
Classic.
