Peter Budai has established himself as one of the world's leading origami creators. This small booklet was written when he was 12 years old, and is not really on par with his later creations. Most models are multi-part, using sheets different in size, and rather crude in appearance. Since there are other dinosaur books around, I wouldn't recommend this book for pursuers of the subject, and if you like Budai's work - you'd better stick to his newer excellent books.

Other then that, the diagramming quality is very good, and there's a black-and-white photo of every model.
