Year of International cooperation - 65 fils
This commemorative postage stamp was issued in 1965 by the Federation of South Arabia, a British protectorate established in the southern portion of the Arabian Peninsula centered around Aden. By releasing this dedicated postal issue, the regional administration participated in a global omnibus philatelic observation, formalizing its connection to broader international bodies and aligning its local civil network with global civic initiatives.
The issue was released to mark the United Nations' International Co-operation Year (ICY), a global initiative designated by the UN General Assembly for 1965. The event was established to celebrate the 20th anniversary of the founding of the United Nations and to direct public awareness toward the extensive, often unheralded achievements in multilateral diplomacy, scientific advancement, and economic development taking place between member nations worldwide.
