I got this book to get some more backgound info on postmodernist conceptualism and where Duchamp actually fits into it all. I got a lot more and am beginning to realise that DADA was fairly seminal in the progression of abstract expressionism and pop-art and the move away from cubism. which I did not know before. Iconoclastic, possibly, but DADA is not without plenty examples of thought and reflexion in art making. There are plenty of colour photos with a good biographical section at the back. Representing over 120 artists in the movement, this is a comprehensive volume on the subject with each work properly annotated and very informative.
