This classic 10 lepta red stamp from Greece belongs to the “Small Hermes Head” definitive series, issued between 1911 and 1923. It features the profile of Hermes, the messenger of the gods, rendered in a finely lined classical style. Printed typographically, these low-value definitives saw heavy postal use across Greece, making attractive, well-struck cancellations—like the bold circular postmark on your example—especially collectible. The series is valued for its numerous printings, subtle shade varieties, and plate differences, offering rich opportunities for specialization. A solid used example of an iconic Greek definitive issue.
