Issued by the République Française in 1962, this 0.50 franc stamp was part of the global campaign led by the World Health Organization to combat malaria. The striking design by Albert Decaris and P. Gandon depicts a stylized mosquito beneath the WHO emblem, set above a serene marsh landscape — a symbolic reminder of the disease’s origins and the world’s united response. The red and blue engraving emphasizes vigilance and cooperation in public health. This issue is highly regarded among collectors for its powerful message and fine intaglio detail.
