The listing, The Illustrated Encyclopedia of Sex has ended.
Although this book was a revised edition published in 1965, it contains relative, basic and advanced information about human reproductive organs of the male and female and the function of each. Amatomy never changes so the book still containsd good information and illustrations. It will make a good addition to an educational library. It is a hardback , the spine and pages of the book are intact but the pages due have some signs of age, which is understandable.
