Found this book today, in a shop selling used books. Seems a nice, general reference book.
Titled:
Contemporary Polish Posters In Full Color
Published in 1979, and features 46 full color plates of Polish posters, from film, plays and concerts. The posters were selected by Joseph S Czestochowski. He also wrote the introduction.
Synopsis:
"The traditions of Polish graphic art and the influences of folk culture, nationalism, and European art movements are evidenced in a collection of posters created by Polish artists from 1961 to 1977. This superb collection includes 46 full-color examples from the brilliant school of Polish graphic design, selected from the world's first museum (Muzeum Plakatu in Wilanow) dedicated to poster art. Vivid, striking colors and unusual themes-- including theater, sports, circuses, films, concerts -- all show cosmopolitan influences, free imagination."
