I would say this is more of a production diary from one of the artists. Included are some concept art, paintings and storyboards.
The book details the journey for creating the animated movie. It's like how the artists look at their work and think about what they have done, how far they have come. It's more emotional talk than technical talk.
I wish they had included more art because they are terrific.
It's great that this book is going to be reprinted again, since its first publication in 1939. It's a very useful book.
All the concepts of perspective are explained in plain and simple English. It teaches the basic foundation well, in a progressive manner where you build onto what you've learned earlier. Included are examples that emphasis the lesson point effectively. Once you get it, you get it forever.
