Inauguration of the WHO Headquarters Building in Geneva - 3 piastre
This commemorative postage stamp was issued in 1966 by Sudan as part of a worldwide philatelic observation. By issuing this dedicated postal release, the post administration joined member states across the globe in highlighting the nation's formal integration into United Nations bodies and international civil health networks.
The issue was released to mark the official inauguration of the new World Health Organization (WHO) Headquarters Building in Geneva, Switzerland, in May 1966. Designed by Swiss architect Jean Tschumi, the opening of this centralized facility marked a major milestone for the WHO, unifying global public health administration, research, and international disease control initiatives under a single landmark location.
