The Cold War period is often thought of as a period of non-porosity between West and East. However, cultural objects discovered before the establishment of socialist governments continue to circulate. Based on the work of Czech author Kája Saudek, we propose to study how American comic strips were adapted, reworked and transformed in communist Czechoslovakia in the 1960s. Saudek collaborated on a classic of Czech popular cinema, Kdo chce zabít Jessii? (Who Wants to Kill Jessie?), directed by Václav Vorlíček. At the same time, he worked on a more personal project, the graphic novel Muriel a andělé (Muriel and the Angels) written by Miloš Macourek and inspired by the French comic strip Barbarella. This article looks back at the atypical work of a monument of Czech comics, at the crossroads of various influences in a world split in two blocs.
