From what I can gather Le Livre de la Sante or The Book of Health or the Encyclopedia of Mind, Body and Health by Joseph Handler was a multi-volume series of text books on science, anatomy, biology, psychology and health intended for use in the classroom. Reading these text books must have been a blast as page after page is filled with the most beautiful day-glo colored illustrations by an incredibly diverse range of artists and graphic designers.

Published in Monte Carlo between 1967 and 1969, Le Livre de la Sante was also made available in an Iranian edition—which kinda shows how hip Iran was back then. Handler’s educational books are still available to buy—and 50 Watts has uploaded a whole library of pages from these books which can be viewed here.
