Color illustrated and printed on card stock for the year 1938. Published jointly by the former rival trade unions, the anarcho-dynicalist Confederación Nacional del Trabajo (CNT) and the national socialist union Union General de Trabajadores (UGT) with the premiere illustration in January showing members of the two organizations embracing each other. Each page features a large color illustration of a battle scene - unsigned, but all by the same artist - and below a short biography of a fallen worker-soldier, along with a portrait, a long list of events of the month.
Group of 18 (of 20) original color-printed postcards with Baker's signature of verso. Each was published in Barcelona as a joint project of the Catalan socialist party and the National socialist worker's union. Includes graphic work by Lleó, Parriego, Subriats, Michael Adam, and Marti Bas. Most are reduced images from larger posters.
