Trade paperback, NOT the smaller mass-market size. Special collectible edition arranged by Quality Paperback Book Club (Book-of-the-Month Club) with Houghton-Mifflin, prior to Peter Jackson's movies. Features a large, beautiful, detailed, tip-in map of Middle Earth. This map of Middle Earth is often printed on the first few pages of editions of The Lord of the Rings, but this particular map is a separate sheet, and large enough to be folded several times.
