This Polish postage due stamp features the bold national emblem of Poland – the crowned White Eagle – rendered in deep red. Issued as part of the mid-20th century postage due series, it carries a face value of 20 złotych and the word "DOPŁATA" (meaning "postage due") at the base. The ornate scrollwork framing the eagle enhances its regal appearance, symbolizing Poland’s resilience and national pride. Such stamps were used to collect insufficiently paid postal fees, making them an essential part of Poland’s postal system history.
