This striking 15-cent stamp was issued by the United Nations in 1972 to mark World Health Day. The design features Leonardo da Vinci’s famous Vitruvian Man, symbolizing the harmony of body and health, set against bold modernist red, orange, and blue panels. Above sits the UN emblem, reinforcing the organization’s mission toward global well-being. A meaningful issue that bridges Renaissance science with modern health advocacy, it holds strong appeal for collectors of UN philately, medical themes, and health-related commemoratives.
