Captivating photography. Gripping editorial. They are the hallmarks of National Geographic, the esteemed periodical that has been fascinating and educating readers of all ages for 125 years. To commemorate this milestone, the National Geographic Society has authorized this awe-inspiring three-volume National Geographic books set. Massive in both size and content, each book is a mammoth pictorial timeline, and includes many previously unpublished photos. Covering the Americas, Europe, and Asia and Oceania, the volumes are each individually housed in a hard slipcase, which doubles as a convenient reading perch. Hardcover; approx 500 pages, each.
