The Hobbit & The Lord of the Rings Box Set
by J R R Tolkien
If you’re looking for a good, reasonably priced Lord of the Rings boxset, this is a good choice. The cover images of each book are by JRR Tolkien himself and the books include maps by Christopher Tolkien, his son. At the end of The Return of the King, there is also an index (useful as not only are there many characters in Lord of the Rings, but many have more than one name).
