A rare book by a famous author of educational literature for artists. A large number of illustrations (560), in which the structure, proportions, movements of many animals are analyzed in detail. The brilliant constructive drawing of the author very well contributes to understanding how to "build" the body of animals, how to transfer volume, take into account promising reductions, not be distracted by small details without building the main masses, etc. In general, a book from the category necessary for the artist.
