Issued in 1955 by the United Nations Postal Administration (UNPA), this 30-cent stamp powerfully embodies the UN’s founding vision of international solidarity. Featuring the motto “To unite our strength”, the design depicts a series of stylized, colorful flags converging together—symbolizing cooperation among diverse nations under the UN banner. The emblem of the United Nations appears in the upper left, reinforcing the organization’s global mission for peace and unity. This issue remains a classic mid-century representation of postwar optimism and internationalism.
