This powerful design promotes a European trade union and workers conference held in East Berlin. Because of its location, only laborers from within the Eastern Bloc would have been in attendance. The design is dominated by the oversized red leg of a Communist worker crushing the skeletal form of a Teutonic Knight—a symbol associated with German nationalism and the Nazis—clutching a modern warplane. The Communist conflation of Fascism with capitalism often led to Nazi symbols being used interchangeably with those for the West. Like other posters produced under Soviet direction, the emphasis here is on the need to curtail the West from further developing nuclear technology rather than heralding the glory of Soviet nuclear research.
