This Paraguayan commemorative stamp was issued in 1962 as part of the global “World United Against Malaria” campaign led by the World Health Organization (WHO). The design features the WHO emblem — a serpent entwined around a staff before a world map — alongside a stylized mosquito, symbolizing the fight against the disease’s primary vector. Printed by De La Rue de Colombia, the 0.30 guaraní issue uses clean geometric imagery and a pink background to underscore global solidarity in public health. A fine thematic piece for collectors of WHO, medical, or anti-malaria issues.
