The spectacular images by Alfonso chosen for this monograph are part of the Spanish collective graphic memory. Their photographs have helped us reconstruct the history of a tumultuous century marked by the war in Morocco, the fall of the monarchy in Spain, the development of the workers' movement and the disasters of the Spanish Civil War. With outstanding technical and aesthetic skill and the incredible talent of capturing everyday life within the historical context, the Alfonso studio revolutionised Spanish photojournalism and anticipated documentary photography.
