This 25 zł stamp from Poland, issued in 1989, features the English Setter (Seter angielski), a well-known hunting dog breed admired for its elegance, stamina, and gentle temperament. The design presents a detailed portrait of the dog’s head with its mouth open, alongside a smaller full-body illustration at the top. Printed by PWPW (Polska Wytwórnia Papierów Wartościowych) and designed by J. Wysocki, this issue belongs to Poland’s series showcasing popular dog breeds. A fine piece for collectors of canine-themed philately, zoology issues, and Polish definitive art of the late 20th century.
