This French 0.50 franc stamp was issued in 1962 as part of a global campaign against malaria. The design features reeds and a swamp landscape in blue, symbolizing mosquito breeding grounds, with a striking red mosquito overlaid by the World Health Organization emblem. Inscribed “Le Monde Uni Contre le Paludisme” (“The World United Against Malaria”), it highlights international solidarity in fighting the disease. A strong historical issue, it reflects France’s participation in the worldwide health effort of the early 1960s. Highly sought after by collectors of medical themes, WHO issues, and French commemoratives.
