I bought "Marx for Beginners", a cartoon introduction to Marx written by Mexican political cartoonist Eduardo del Rio ("Rius"), not so much because I needed an introduction to Marxism but to see how the theory can be summarized as pithily and shortly as possible. And indeed, Del Rio has done an admirable job on this. The reader is guided through all aspects of Marx' work as well as biography, even including an extraordinarily rapid overview of the history of philosophy and of the early socialists. Of the economic theories of Marx only the basics are explained, but nevertheless sufficient to get the point of what Marx tried to show in "Capital", if not how he proved it.
As far as the political side goes, Del Rio usefully emphasizes the limitations of social-democracy and its inability to get beyond the exploitation of capitalism, as well as many quotations from Marx showing how he opposed this tendency. As criticisms, one could remark that Engels gets short shrift in this book - admittedly it is titled "Marx for beginners", but one wonders why not "Marx & Engels for beginners"? Also, Del Rio seems to take the connection between Marx and Lenin as a natural progression for granted, even including in the (otherwise very handy) vocabulary of terms under Marxism-Leninism: "theory of the proletarian liberation movement". Hardly something uncontested.
The drawings are clear and funny, if a bit on the juvenile side compared to the content that he is trying to convey. This might have a good effect on younger people reading it though, making it possibly useful as a high school text on Marx, if there ever is a capitalist country brave enough to allow it. Due to the requirements of Del Rio's purpose, some of the summaries of earlier thinkers are so simple as to be simplistic, but this can't be helped. Overall, a practical and well-done introduction to Marx for the complete novice.
