This article analyzes the last three years of existence of the weekly paper published in Barcelona L´Esquella de la Torratxa (1936-39), years that also coincide with the Spanish Civil War. During this period the paper suffered a political transformation since it became the official paper of the Union of Professional Cartoonist of the Worker’s General Union (UGT). Therefore this article will explore the changes the paper underwent in its transition from a paper whose satirical punches were aimed at the bourgeoisie and the conservative Catalan government of Cambó and his party, La Lliga Catalana (The Catalan League), to a propaganda paper in the hands of the Worker’s General Union (UGT).
