Cyrk - contemporary Polish circus posters, emerged in 1962 as a genre of the Polish School of Posters. They are characterized by their display of aesthetic qualities such as painterly gestures, linear design, hand-lettering, metaphors, humor, and vibrant colors. Usually based on a single theme and meant to be advertisements; they were created in an attempt to interest the passerby in the upcoming circus. Several Polish painters contributed to establishing the art style, among them Henryk Tomaszewski.
