The images used to illustrate The Joy Of Sex (1972) had to be drawings in order to avoid obscenity charges. The couple featured in the book was one of the illustrators, Charles Raymond, and his German wife, Edeltraud:
The pictures delighted author Alex Comfort, partly because Charles and Edeltraud looked so natural and unposed, absorbed in their private sexual relationship. "The great thing about Charles and his wife was that they were completely authentic – you couldn't get more authentic," says [art director Peter Kindersley]. "It was a real happening – it wasn't a cooked-up thing – and Alex really liked that."
