Czechoslovakia 1 Koruna Postage Due Stamp

This item is a vintage postage due stamp from Czechoslovakia, specifically a 1 Koruna denomination. The stamp features a rectangular shape with intricate ornate borders, primarily in dark blue ink on a lighter background, likely white or off-white paper. The central design element is an oval or circular frame enclosing the large numeral '1' and the word 'KORUNA' beneath it, indicating its value. Above the central design, the word 'CESKOSLOVENSKO' (Czechoslovakia) is prominently displayed, and at the bottom, 'DOPLATNE' (Postage Due) is written, signifying its purpose. The design exhibits classic philatelic engraving or printing techniques with fine lines and decorative flourishes. The stamp is machine-canceled with a circular postmark, parts of which are clearly visible, covering a significant portion of its surface, indicating it has been used. The postmark appears dark, possibly black or dark blue ink, and obscures some of the underlying design, particularly the right side and upper right corner. The edges of the stamp show typical perforations, though some appear slightly separated or worn, hinting at its age and handling. There are no immediate visible tears or major rips, but the overall crispness and color saturation are somewhat diminished due to age and the heavy cancellation. The paper itself appears to be of standard stamp paper quality from its era. The style suggests it dates from the early to mid-20th century, consistent with the period of Czechoslovakia's existence. The quality of printing seems good for its time, indicative of professional government production for postal services. The postmark extends beyond the stamp's borders onto what appears to be the surrounding paper or envelope, suggesting it was affixed to a mailed item.
