This early Polish definitive stamp, issued around 1919, features the classic crowned White Eagle—the enduring national emblem of Poland—set within an ornate heraldic frame. Printed in a clean blue shade on cream paper, it reflects the transitional post-World War I period when the newly restored Polish state was establishing its own postal identity. Its crisp typographic style and simple vertical lines are typical of the first Poczta Polska issues. Examples with fresh color and full perforations, like yours, remain desirable to collectors of early Polish philately and heraldic designs.
