This book is by the same authors Andras Szunyoghy and György Feher, who also wrote another very similar book called Human Anatomy for Artists, which I also have. This book is thicker at 604 pages and focuses about 200 pages on human anatomy.
If you already have Human Anatomy for Artists and not interested in the drawings of animal bones and muscles, you can skip this book. Most of the illustrations inside have actually appeared in the other book. The only additional part I see is some additional drawings of drapery. The main difference is the other focuses on every single muscle with many different views, this book also has those muscles but in lesser but the basic view ' front and back. Bones still have as many views and come with muscle attachment points.
Illustrations of bones and muscles are very big and clear. The animals featured are horse, dog, cat, pig, monkey, sheep, bear, deer, cow, camel and lion. A big bulk is on horses. It's really interesting to see how different the bone and muscle structures are in different animals. I don't have any other animal anatomy books to compare from but this one's pretty good.
This is a very useful anatomy reference book.
