Issued in 1973, this commemorative stamp from the République Populaire du Congo marks the 25th Anniversary of the World Health Organization (OMS/WHO). The design features the WHO emblem with the serpent-and-staff symbol over a light blue UN globe, boldly highlighted by a red “25ème Anniversaire” inscription. Printed in clean teal and white tones, the stamp reflects the nation’s participation in global public health efforts during the early 1970s. A desirable thematic item for collectors of medical history, United Nations agencies, and African post-independence issues.
