This contains the map of Frodo's journey with all the key locations marked from the book.
Here is a sample picture of Frodo's journey towards Weathertop, each day is marked on the map.
It also contains Bilbo's journey from the Hobbit, with Frodo's overlaid in brown to show differences in route and time taken.
If memory serves other events including those from the Silmarillion such as Beren and Luthien's journey into Angband, the Westward migration of the various tribes of Men and the Host of the Valar coming East to finally deal with Morgoth.
As to whether these are artistic or interesting, this will be personal opinion but I think they are very well drawn, with enough of the flavour of the maps that Tolkien drew.
Stylistically I think it compliments Tolkien's work and is a good visual aid when reading the books.
I have also found the information very interesting, and there is a lot of it too.
