Issued by the United Nations Postal Administration in 1981, this 18-cent commemorative stamp marks the 10th anniversary of the UN Volunteers (UNV) Programme, founded in 1970. The striking design features a stylized tree growing from concentric rings resembling those of a tree trunk, symbolizing growth, sustainability, and the expanding impact of volunteerism. At the center lies the UN emblem, representing the organization’s global outreach and dedication to humanitarian service. The clean, modern layout and earthy palette capture the essence of development through cooperation.
