International Co-operation Year- 3 piastre
This commemorative postage stamp was issued in 1965 by Sudan as part of a nationwide philatelic observance. By releasing this dedicated postal issue, the post administration participated in a worldwide omnibus initiative, highlighting the country's active involvement in United Nations affairs and formalizing its connection to broader international administrative frameworks.
The issue was released to mark the United Nations' International Co-operation Year (ICY), designated by the UN General Assembly for 1965 to coincide with the 20th anniversary of the UN's founding. The global event was established to direct public attention toward multi-nation collaboration, celebrating international achievements in diplomacy, peacebuilding, scientific sharing, and joint economic development.
