Picasso - El Toro - Pablo Picasso created 'El Toro' at Christmas 1945. 'El Toro' is a set of lithographs that have become a master class in how to develop a work of art from the academic to the abstract. In this series of images, all resulting from a single piece, Picasso visually dissects the image of a bull. Each image represents a successive phase of a process aimed at finding the absolute "spirit" of the beast. It is as if he were walking from front to back, from finished to sketch.
