This striking semi-postal stamp from Poland (Polska) features a vivid 15th-century stained-glass panel from Kraków, reproduced in deep reds and golds to highlight the medieval artistry of the region. Issued with a surcharge for charitable purposes, the stamp presents a haloed figure reading from an open book, a classic depiction of Gothic religious iconography. The crisp rendering of the leaded glass structure makes it a standout thematic item for collectors of art, religious imagery, and Polish cultural history. A highly desirable piece for those building a Poland semi-postal collection or focusing on architectural art.
