This 40 lepta definitive stamp from Greece features the iconic White Tower of Thessaloniki, a landmark symbolizing the city’s Ottoman and Greek heritage. Printed in a fine blue-green engraving, the design showcases ornate side borders and classical Greek motifs typical of early 20th-century Hellenic issues. Part of the long-running “Landscapes & Monuments” definitives, it circulated widely before and after the Balkan Wars period. Collectors value these stamps for their detailed linework, multiple printings, and distinct cancels—this example shows a strong postal strike across the tower. A desirable piece for specialists in Greek definitives or architectural themes.
