This book is hard to come by, but it is worth it if you want the most comprehensive and detailed encyclopedia of tribal African art. There are over 1,000 photos in this oversize 620 page epic overview. Lots of the photos are full color, and large. The book gives an overview of the art, a comparison of aesthetics, and breaks down the types and styles by analysis of every feature you can imagine, and does so in an inspired way.
Part Two - to me invaluable, looks at the art by region where you see the similarities and contrasts of tribes within a geographically relevant part Africa.
