This lovely green book is one part of the International Series in Pure and Applied Physics. As a book on Theoretical Mechanics, it is filled with lots of delightful diagrams, equations, etc.; published in 1954 it is in great shape; there is only one small name written in the top corner of the inside corner. There are no creases and the spine is intact. This would make a great coffee table book or even a textbook, provided that you're nerdy enough to handle it. Enjoy!
