This is a fabulous book!
All the maps are line drawings in simple tones such as black and brick colours - don't expect funky digital maps or a wealth of colours; that, however, does NOT detract from the excellence of this work! In fact - it is a bonus in my view: makes the maps clearer and more precise: it's also a nicer "feel".
I have sat and studied some of these maps for ages - and they really bring to life the travels of Frodo, Bilbo and the Fellowship in great detail. You get info right down to climates of the regions! I was enthrawled for who knows how long on the Moria maps (my favourite Tolkien place!) and it really gave depth to the extent of the journey the Fellowship took.
This is simply a MUST, not just for staunch Tolkien fans but as a trusty companion to the LOTR books for any reader (along with a Tolkien dictionary/encyclopedia).
You will be so glad you invested in it.
