National Geographic Society Atlas Folio. All regular maps of the Atlas Series listed are numbered and grouped by regions. Plate number will be printed on each map beneath the title. Includes a "how to assemble page". Very detailed and colorful maps of the world. Large atlas, hardcover. 14" X 20". Very good condition, the cover has some marks on it, but the maps are nice. Sorry about the picture, it certainly doesn't do the atlas justice. I have to use a camera phone...You won't be disappointed.
