In his cartoons, Dürrenmatt often alludes to various events of his day. For example, in the My Poster Homeland series (1963), he applies caustic wit to the typhoid scandal in Zermatt. Several of his ink-and-pen drawings also deal with contemporary history: his St. Tropez (1958) drawing comes to mind, with its acts of violence during the Algerian war serving as a backdrop for the composition’s central scene. In his collages Portrait of a Planet II (1970) and The Physicists II (1973), Dürrenmatt addresses the war in Vietnam and space exploration.
