First published in the 1970s, this book was the brainchild of the Mexican cartoonist Rius, who proved that the comic book format could be serious and informative as well as entertaining, by creating a friendly book on an indigestible subject, Karl Marx. Karl Marx went out of fashion when the Berlin Wall came down and the socialist command economy in Soviet Russia and its satellites collapsed. But did Marx prescribe anything like the Soviet bloc model of socialism? Answer? No. For 70 years, his critique was the captive of a model that he would not have recognized or approved. Great thinkers like Marx do not go away. Soon enough, he will be rediscovered, and this book provides a useful introduction to a philosopher who is more than ever relevant now as the world moves towards unregulated free market economies.
