This classic Greek postage due stamp features the denomination 3 Λέπτα prominently within an ornate frame inspired by classical Greek architectural motifs. Printed in a vivid red-orange, it belongs to the long-running “ΕΝΑΡΊΘΜΟΝ ΓΡΑΜΜΑΤΌΣΗΜΟΝ” (Numbered Postage Due) series, issued in the early 20th century to indicate fees collected on unpaid or short-paid mail. The design shows scrollwork, columns, and geometric patterns characteristic of Hellenic revival engravings. A desirable item for collectors of early Greek fiscal and postage due issues, especially in clean, well-centered condition like this example.
