This 1977 Greek commemorative stamp (ΕΛΛΑΣ, 30 δραχμές) highlights the growing global concern for environmental protection during the late 20th century. The design contrasts a classical Caryatid—symbol of Greek heritage and cultural endurance—with stark industrial silhouettes and rising smoke plumes, representing the threats posed by modern pollution. Issued as part of Greece’s environmental awareness efforts, the stamp stands out for its bold, almost poster-like graphic style and its strong social message. A meaningful thematic piece for collectors interested in ecology, environmental history, or Greek cultural symbolism on stamps.
