These postcards were drawn by the political cartoonist Kem (Kimon Evan Marengo 1907-1988), who during the Second World War produced over 3,000 propaganda cartoons for the British Ministry of Information.
Kem prepared these between March and October 1942. The illustrations are based on five scenes from the Shahnameh of Ferdowsi. The battle between the Allies and the Axis powers was depicted here as the mythical battle between Fereydoon and Zahhak.
FYI: Fereydoon = good guy; Zahhak = bad guy with serpents growing out of his shoulders. In this series, Hitler is Zahhak. Click here for more.
