One of my favorite art sources, the Polish Poster Gallery, features vintage and contemporary, original posters designed for movie, theater and music events. The list of artists includes the most famous graphic designers: Cieslewicz, Czerniawski, Stasys, Gorowski, Klimowski, Lenica, Mlodozeniec, Olbinski, Pagowski, Rosocha, Sadowski, Sawka, Starowieyski, Swierzy, Tomaszewski, Urbaniec, Walkuski and others.

Pictured here is one of a series of circus posters designed by Wiktor Gorka, a Polish artist whose body of work spans theatre, movies, advertising and propaganda. Highly recommended.
