Issued by Iceland in 1973, this commemorative stamp celebrates the 100th anniversary of international meteorological cooperation (1873–1973), marking the origins of modern global weather science. The modern graphic design features a stylized human silhouette set against clouds and horizon bands, symbolizing mankind’s relationship with atmospheric observation. The United Nations–style emblem highlights global scientific collaboration in meteorology. Its minimalist Nordic design reflects the strong Scandinavian tradition of modern postal art. This issue is especially attractive to collectors of science, environment, and UN-related thematic stamps.
