J.R.R. Tolkien: Lord of the Rings 'Middle-earth' unveiled
It is a fantasy land through which millions have walked in their own imaginations.
Now fans of Lord of the Rings can see Middle-earth as its creator J.R.R. Tolkien did.
A previously unseen map, drawn by the author's son Christopher and added to by Tolkien himself, is going on display for one day only.
