As a teacher of drawing, I have read many books on the subject. This book is the only one I would use as a textbook. I would agree with all the previous reviews but would only comment on the one review from the budding artist who felt the book is confusing and has too much art history for someone who only wants to learn to draw. I come to this book with over two decades of art experience so maybe that is why I find it so interesting, but even if the history is skipped and you read only the practical explanations and do the lessons in the back of the book, you will learn to draw from observation, as this book promises. The book is not meant to be read in two weeks. Learning to draw takes hard work and invested time.
