This striking red stamp from Poland was issued for official registered government mail (noted by the inscription “Przesyłka Urzędowa Polecona”). It prominently features the Polish crowned eagle, the enduring national symbol, framed within a richly ornamental border. Such official service stamps were used in the early 20th century and remain highly collectible due to their restricted postal usage. A fine piece of Polish postal history, this stamp appeals to specialists of official issues and lovers of classic Polish designs. A desirable addition for those curating an Eastern European collection.
