A striking modernist design issued for the World Philatelic Exhibition in Warsaw, celebrating global stamp collecting culture. The bold black graphic forms and rainbow-striped spool symbolize threads connecting collectors worldwide. Designed by W. Freudenreich, the artwork reflects Poland’s strong 1960s poster-art aesthetic. The large 65 zł denomination and exhibition theme make it a standout topical piece for philately collections. Ideal for exhibition, art-design, or thematic “stamps on stamps” albums. A vibrant and eye-catching addition with strong visual appeal.
