This is an excellent book, the best of its kind. If you want a good introduction to Northwest Coast native art, this is the one to get. I have a few, and this is the best for an introduction and overview. Not only does it have fantastic pictures culled from a variety of locations, but the pictures are actually cued to the text (not as prevalent as you might think!). The discussion of the movement from the pre-historic culture to a museum culture and after is fair and well-balanced and insightful about tourism, museology, and so on. And a decent map!!! Altogether great.
