This 6-cent United Nations stamp, issued in 1971, promotes the peaceful uses of the sea-bed beyond national jurisdiction. The design features stylized blue ocean waves, a school of fish, and the UN emblem, symbolizing both marine life and international cooperation beneath the seas. The theme reflects growing global concern in the late 1960s and early 1970s about regulating seabed exploration to prevent militarization and environmental harm.

Issued by the UN Postal Administration in New York, it commemorates discussions that eventually led to the 1982 United Nations Convention on the Law of the Sea. This issue stands as an emblem of early international environmental and disarmament efforts.
