From the dust jacket:
This is essentially a children's book, which contains a poem and paintings detailing Bilbo's last journey, in addition to scenes from "The Hobbit" and "The Lord of the Rings" trilogy. The paintings are constructed by Pauline Baynes, who was Tolkien's favourite illustrator. She also illustrated Tolkien's "Farmer Giles of Ham", "The Adventures of Tom Bombadil", "Smith of Wotton Major" and "Tree and Leaf." In addition, she also illustrated C.S. Lewis' "Narnia" books. I enjoyed the illustrations, but was not blown away... as with the work of another famous Tolkien illustrator, Alan Lee.
The book is really meant for Tolkien enthusiasts and without the Tolkien name and paintings [accurate to Tolkien's stories], it would be truly forgettable. With these additions and descriptions at the end of the book pertaining to the paintings, this is a nice little journey to take your mind back to the adventures of Bilbo.
Note: There are many versions of this book, and even the version shown in this post has both large and small formats. If you are purchasing the book online, make sure you check the dimensions.
