Not bad -- Maybe a high 3 -- I'm not going to finish this, and will mark as 'get-the-picture' (no pun intended)
I was completely wrong about this book - there is a lot of good material in it. I am now in the chapter on Futurism, Dada, and Surrealism, and learning a lot. The book is not well organized - the writer wanders about, and the prints are out of place -- he talks about early Chagall in the section on Dada (Post WWI), and later Chagall in the section on Cubism, and prints the the pictures of Miró and Max Ernst (late 20's) while talking about the late-teens. So one has to work with the author in a very annoying fashion. He also seems to think the Anglo-American culture of 1959 (the year of the first edition) is still essentially futurist -- But that said, the book is well worth some time...
