This 1979 Greek definitive shows the rugged volcanic cliffs of Glaronisi, a small islet near Milos in the Cyclades, famous for its dramatic geological formations. The stamp captures the island’s steep ochre-and-grey rock faces above the deep Aegean waters, reflecting the volcanic origins that define this region. Issued by Hellas (ΕΛΛΑΣ) in the lower drachma values, it belongs to a scenic series highlighting the natural beauty of Greece’s coastline and islands. Clean lithographic printing and fine colour detailing make it a popular addition for collectors of Greek landscapes and Aegean geography.
