This is a National Geographic Atlas of the World Enlarged Second Edition published in 1966.  This is a hardcover book with a nice case.  It has a total of 343 pages. Besides the maps there are pages of Temperatures, Populations, Abbreviations, Earth in Space, etc.

It is large, measuring 13 x 19 inches and is in very good condition. There are a few small scuff marks along the edge of the case, but the book itself is in pristine condition. The binding is intact and there are no pencil/pen marks. It actually was probably not opened very much at all.

This comes from my parent's estate and has my father's name imprinted on the cover.
