Marvelous!!! Handmade by Peter Goebel. Made with brass covers and genuine ivory pages, it is similar to Thomas Jefferson's, but with the addition of a pencil. The four pages measure about 5/8" by 4". The ivory used is taken from recycled piano keys which are approximately 150 years old. The overall size is about 1" wide by 4 1/2" long. The pencil takes a 1/8" lead (included) and holds the notebook closed in your pocket.
