Issued by the United Nations Postal Administration in 1981, this 18-cent commemorative stamp marks the tenth anniversary of the United Nations Volunteers (UNV) Programme, established in 1971. The design features a stylized tree growing from concentric rings resembling the cross-section of a tree trunk — symbolizing growth, renewal, and the expanding impact of volunteer service. At the center lies the UN emblem, signifying the program’s global reach and its roots in peace and development. The minimalist layout and earthy color palette embody the spirit of sustainability and human solidarity that the UNV represents.
