These striking Greek commemoratives were issued in 1966 to mark the International Astronautical Congress held in Athens. The set captures the excitement of the early Space Age with bold, modernist designs.

• The 2.50 drachma stamp features an astronaut in a silver space suit floating weightlessly, symbolizing humanity’s first steps beyond Earth.

• The 6 drachma stamp shows a rocket and capsule orbiting the moon, evoking both U.S. and Soviet space achievements of the era.

The inscriptions “Αστροναυτικόν Συνέδριον – Αθήναι” (Astronautical Congress – Athens) highlight Greece’s role in hosting this prestigious scientific event. Designed in vivid blue tones with stylized linework, the stamps celebrate the universal spirit of exploration.
