Huge, very heavy book of almost 400 pages. Wonderful reproductions in color of their work, and, for the most part, easily understood prose. I think I learned a lot. I know I learned that I like Picasso better than Matisse, whom I found to be basically cold and severe, too intellectual in his art. How he was personally this book does not say. You do get a little more sense of Picasso than Matisse. The book focuses on how these two artists played off each other's work almost all their artistic lives. And as such, it definitely succeeds. It was actually printed in conjunction with a major exhibition of these two, in Paris, London, and New York. A must for all art lovers.
