The Lord of the Rings Film Artbooks (English)

The Art of The Fellowship of the Ring

The Art of The Two Towers

The Art of The Return of the King

The Art of The Lord of the Rings

These are the official artbooks for the Lord of the Rings films. One book for each film, and a fourth compilation book that has material that wasn't included in the first three.

There are already PDFs of these books floating around, but they're in Chinese. These are in English and in better quality.
