This is a stimulating source book containing a lot of interesting visual material and a handful of quite stunning images. The text is not particularly informative and I'm guessing is aimed at beginning students, aiming to teach them some big new words for quite straightfoward things. Much of the text is in the form of lists which, apart from those giving the names of interesting artists to follow up, are not terribly informative. The book has not taught me how to do anything new or triggered any great flashes of insight or inspiration. However, it did point me towards the work of George Grosz, who has become my new current favourite 20th Century artist. I can imagine that I will browse the images in this this book again from time to time. Useful but not amazing.
