Inauguration of W.H.O. Headquarters, Geneva - 10 fils
This commemorative postage stamp was issued in 1966 by the Federation of South Arabia, a British protectorate in the southern portion of the Arabian Peninsula centered around Aden. By issuing this dedicated postal release, the regional administration participated in an international omnibus philatelic observation, formally aligning its civil communication network with international organizations and global public health initiatives.
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 the Swiss modernist architect Jean Tschumi, the opening of this centralized complex represented a major milestone for the specialized United Nations agency, consolidating global health logistics, epidemiological research, and international disease eradication campaigns under one roof.
