This 10 centimes commemorative stamp from the République du Congo was issued in 1961 as a tribute to Dag Hammarskjöld, the second Secretary-General of the United Nations, who tragically died that same year in a plane crash while on a peace mission to the Congo during the country’s crisis following independence. The design, printed by Courvoisier S.A., features Hammarskjöld’s portrait against a map of Africa, symbolizing his deep involvement in UN peacekeeping in the region. The UN emblem appears at the lower left, reinforcing the theme of international cooperation and peace.
