Issued by Poland in 1983, this 30 złoty commemorative stamp honors the Polish painter Wojciech Weiss (1875–1950). The design reproduces one of his impressionistic works, Flowers by the Window, capturing a vibrant bouquet in a vase rendered with Weiss’s characteristic play of color and light. The stamp belongs to a series celebrating notable Polish artists and their contributions to national art heritage. It beautifully combines fine art appreciation with philatelic artistry, making it a prized piece for collectors of art-themed issues.
