This Polish postage stamp, issued in 1989, features the Welsh Terrier, a lively and courageous dog breed known for its wiry coat and cheerful temperament. The design by J. Wysocki beautifully depicts a close-up portrait of the dog, complemented by a smaller full-body illustration above. Part of a thematic series showcasing popular dog breeds, it highlights Poland’s tradition of celebrating animals through philately. With its clear denomination of 20 złoty and the inscription Polska, this stamp appeals both to canine enthusiasts and collectors of zoological themes.
