This older book was put together in 1939 by Rudolf Kronfeld and it is the 2nd edition thoroughly revised. There is no dust jacket and is almost 500 pages weighing around 2 pounds. The previous owners name is on first front page. I actually like the look of this book just for the patina and character. This type of book looks great on bookshelves for display. But it also has some very interesting information about the teeth for a dentist and over 400 engravings.
