This commemorative stamp pair issued by the Republic of Congo in 1961 honors Dag Hammarskjöld, the second Secretary-General of the United Nations, who died in 1961 while on a peace mission in Africa. The stamps depict his portrait set against the outline of the African continent, accompanied by the United Nations emblem, symbolizing his role in international peacekeeping efforts. Issued in denominations of 6.50F and 8F, the set reflects global recognition of Hammarskjöld’s diplomatic contributions and his lasting influence on UN peace initiatives. These memorial issues are widely collected within both UN-thematic and African independence-era philatelic collections.
