I remember when I finally laid my hands on a reproduction of a 1939 Astounding Stories magazine. I had read so many essays by Isaac Asimov and others that talked about how the 1939-45 era of Astounding was the Golden Age of science fiction. At last! I thought. I have found a precious document!
And I opened the magazine, and my eye fell on the face of a shocked-looking, open-mouthed boy with the headline, “Did you say JOCK ITCH?!”
Also: Ads for anthropological studies of Polynesian sexual rituals. I suspect those studies did not appear in proper peer-reviewed scientific journals.
