This is far from the "be-all, end-all guide to art of the past 100 years." In fact, while it does cover a huge number of artists superficially, it leaves out an equally huge number of extremely important 20th century artists, particularly 3-dimensional artists. Where is Ernest Trova? Claude & Francois Lalanne? Chihuly? Where, in God's name, is Duane Hanson, the first and best 3-dimensional Hyperrealist? If you want a superficial and not particularly daring look at 20th century art, this is a decent choice. It is not, however, anything approaching "be-all" or "end-all."
