Issued by Greece in 1968, this 6 Drachmai commemorative stamp marks the Ethnikon Synedrion “G.A.P.A.” held in Athens. The design features a stylized ceremonial bowl with three rising flames, symbolizing unity, enlightenment, and national purpose. Rendered in soft blue and terracotta tones, the composition reflects the clean graphic style of late 1960s Greek issues. The bilingual layout (Greek text and “Hellas”) enhances its international philatelic appeal. A strong thematic addition for collectors of conference issues, symbolic art, or modern Greek commemoratives.
