This commemorative stamp set was issued by Greece in 1977 to honor “Apodimos Hellenismos,” meaning the worldwide Greek diaspora. The designs symbolically highlight the global presence and historical migration of Greek people. One stamp depicts ancient Greek ships around the map of Greece, representing historic maritime exploration and settlement. Another shows a world map with radiating lines, illustrating the spread of Greek communities across continents. The third stamp features a globe with the Greek flag, emphasizing the unity of Greeks worldwide while maintaining cultural identity. The set is popular among collectors interested in diaspora themes, maritime history, and modern Greek commemoratives.
