Issued by Greece in 1968, this 4.50 Drachma commemorative stamp marks the 5th European Congress of Cardiology held in Athens. The design artistically combines a classical Greek sculpture with a stylized human heart and medical symbolism, reflecting the blend of ancient heritage and modern science. Printed in a striking red and sepia tone, the stamp highlights Greece’s role as host to a major European medical gathering. The bilingual inscription (Greek and English) enhances its international appeal. A desirable thematic item for collectors of medical, cardiology, and conference-related philately.
