This 0.80 F.s. stamp was issued by the United Nations (Nations Unies) in 1972 to mark World Health Day. The design features Leonardo da Vinci’s iconic Vitruvian Man, symbolizing human proportion, health, and harmony, set against bold red, orange, and pink elements. The UN emblem appears above, emphasizing the organization’s role in promoting global health initiatives. A striking and modernist composition, it highlights the importance of physical and social well-being as part of the UN’s health mission. This issue remains a desirable piece for collectors of topical health, medicine, and United Nations philately.
