Get out your wallets! A map of Middle Earth, personally annotated by Tolkien himself, goes to the auction block.

A recently discovered map of Middle-earth annotated by JRR Tolkien reveals The Lord of the Rings author’s observation that Hobbiton is on the same latitude as Oxford, and implies that the Italian city of Ravenna could be the inspiration behind the fictional city of Minas Tirith.

The map was found loose in a copy of the acclaimed illustrator Pauline Baynes’ copy of The Lord of the Rings. Baynes had removed the map from another edition of the novel as she began work on her own colour Map of Middle-earth for Tolkien, which would go on to be published by Allen & Unwin in 1970. Tolkien himself had then copiously annotated it in green ink and pencil, with Baynes adding her own notes to the document while she worked.

Blackwell’s, which is currently exhibiting the map in Oxford and selling it for £60,000, called it “an important document, and perhaps the finest piece of Tolkien ephemera to emerge in the last 20 years at least”.
