This 20 groszy stamp from Poland belongs to the well-known “Galleon” series issued in the mid-1920s, a classic definitive set portraying a stylized sailing ship framed by ornate Baroque scrollwork. Printed in deep red, this value was widely used in everyday postal circulation, making clean used examples desirable for historical displays of the Second Polish Republic. The lower frame features the Polish eagle, symbolizing national sovereignty after independence. Despite heavy cancellations on your specimen, the design remains clear with good centering and intact perforations, adding to its appeal for collectors of early Poland or maritime-themed stamps.
