Kája and his brother Jan were imprisoned with other Mischlinge (mixed-blood) children in the Nazi concentration camp Luža in GERMAN OCCUPIED Poland]].

After the war, as the Communists dominated government and society behind the Iron Curtain, enforced by the Soviet Union, Saudek was also influenced by American artists Robert Crumb and Richard Corben.

In the 1960s he created comics drawings for the magazine Popmusic Express (Underground Com-comix),[6] as well as illustrations to the scripts by Jaroslav Foglar, Ondřej Neff and others.

The album depicts the story of a young physician Muriel, who meets an angel Ro, coming from a distant future.

[7] In 1971 Saudek contributed to the film Čtyři vraždy stačí, drahoušku (Four Murders is enough, Honey) with his comic drawings.

They began to be more critical of Saudek's collaboration with the popular magazine, gradually restricting his work, and banning it altogether in the mid-1970s.

The Ministry of Interior rejected Saudek's adaptation and refused to allow publication, because the officials thought that the style seemed too "American" and there was too much "shooting" in it.

[1] In the 1980s Saudek also co-created a popular TV series, Okna vesmíru dokořán, together with Vladimír Železný and Jiří Grygar.

[13] In September 2009, three of his works ranked among the top five of Czech comics in a poll organized by the newspaper Mladá fronta DNES.
