Did you folks see this??

"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."
