This striking 1978 stamp from Greece (Hellas) features a dramatic close-up of an ancient theatrical mask, symbolizing the rich tradition of classical Greek drama. Issued as part of the “Anthropina Dikaiomata” (Human Rights) series, the design reflects the cultural importance of expression, identity, and artistic freedom rooted in ancient theatre. The bold contrast and intense facial detail evoke the emotional depth of Greek tragedy. The vertical inscription adds a modern graphic touch to a timeless subject. A compelling thematic piece for collectors of art, theatre, and cultural heritage.
