This striking Polish stamp, issued in 1962, was part of a global campaign led by the World Health Organization to combat malaria. The design features a stylized mosquito, the primary vector of the disease, against a textured background. In the upper corner, the WHO emblem with a mosquito is displayed, reinforcing the international effort. The bold inscription “Walka z Malaria” (“Fight Against Malaria”) emphasizes the theme. Printed in earthy tones of brown and green, the stamp has a 60 groszy denomination and served both as a postal issue and a strong health awareness message. A must-have for collectors of thematic issues on health, WHO, or insects, as well as Eastern European philately.
