Anders Österlin was a Swedish graphic artist, illustrator, and designer whose inventive visual language helped shape the postwar identity of Scandinavian modernism. Trained at Konstfack in Stockholm, he co-founded the influential design collective H55 and later became a member of the artist group 10-gruppen. Österlin worked across poster design, book illustration, and corporate graphics, developing a clean yet poetic style marked by bold color, typographic precision, and playful geometry. His posters for cultural institutions and exhibitions captured the optimism and clarity of Swedish design during the 1950s and 1960s. Beyond his commercial work, Österlin was active as an educator and painter, bridging applied art and fine art with a rare sense of balance and visual integrity.
