This vintage hardcover textbook is in very good condition for its age. Binding is very strong, and the pages are in great shape. There is, however, quite a bit of pencil underlining in the book. This does not interfere with its use at all. There are many black and white illustrations in the book, and a few color ones. The illustrations are wonderful! Pages 139 through 144 are bent. The end papers have yellowed with age. See photos for detail of condition
