Signs of Mr. Plum

Contrary to his family’s expectations and despite having lost one eye, Karol Śliwka leaves his rural home to study art in Warsaw. He decides to be a designer of graphic signs. He fills communist Poland with his works and defines the country’s visual landscape. His signs do not hang in galleries, but are present in Polish homes, in Polish streets, at institutions and workplaces. At the same time, he leads an ordinary family life, which he documents passionately over the years. This extremely gifted artist is still considered one of the greatest sign designers in the world.

Directed by Urszula Morga, Bartosz Mikołajczyk, Signs of Mr. Plum leans on a strong ensemble — Karol Śliwka, Dariusz Dłużewski — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about documentary titles of 2026.
