This soldier is one of the defenders of Madrid as he stands behind a spiked wall labeled with the name of the city. His allegiance is clear. He is holding a magnet labeled with the acronyms of the Confederación Nacional del Trabajo (CNT) and the Federación Anarquista Ibérica (FAI) and he is bathed in their predominant colors - black and red.
The soldier is using a magnet to break apart an anthropomorphic swastika - the international symbol of fascism. The swastika is crying and is wearing a black crown, which may be intended to represent the royalist tendencies of many of those fighting for Nationalist Spain. In addition, the swastika is facing away from the soldier apparently in retreat. Additional cracks in the swastika and its tears indicate the weakness of the fascists - a stark contrast to the determined gaze and rooted stance of the defender of Madrid. This image strongly reinforces the claim of the poster that fascism in Spain is on the verge of defeat.
Like poster 4 in this exhibit, the CNT and UGT (Unión General de Trabajadores) Workers' Control Committee, which operated in Valencia until the Republican Government moved from Madrid to Valencia in November 1936, produced this poster. Consequently, the poster can be dated to the period of the beginning of the civil war in 1936.
