Pharmaceutical Ads from Ridendo magazine

Ridendo was a medical and humor magazine distributed to French physicians from 1933 to 1977. Illustrator Jérôme Dubois has curated a collection of the magazine's covers and content from the 1930s.
This post at 50 Watts shows some gorgeous pharmaceutical ads from that era.
