Waldemar Swierzy is one of the most famous and prolific Polish poster artists, having produced over 2500 posters including countless iconic film posters and Cyrk (circus) posters. He's also known for a series of paintings of jazz legends. Here are some of my favorite designs of his. There's a wide range of style on display here, and these selected posters, with the exception of the APOCALYPSE NOW shown below, don't even really showcase his streak/splatter-paint style that could be considered one of his trademarks. I recently picked a great out-of-print book on Swierzy from the kind folk at Posteriatati in New York. Feast your eyes on these.
