"The Bodleian Library has recently acquired a rare, annotated map of Middle-earth, the fantasy world setting for JRR Tolkien’s novels The Hobbit and The Lord of the Rings. The acquisition was made possible thanks to generous support from the V&A Purchase Grant Fund, the Kenneth Rose Fund and the Friends of the Bodleian."
Interesting - but there's a bit of a blooper here - it says
'Based on earlier designs by Tolkien’s son Christopher, the map was extracted from an edition of The Lord of the Rings in the late 1960s, and served as a working document – used by Tolkien and illustrator Pauline Baynes to develop a new poster depicting Middle-earth'
But of course this map isn't 'based on earlier designs by Christopher' - it was removed from Pauline Baynes's copy of TT; this (and the Mordor map in RK were actually drawn by Christopher (who signed 'em with initials), and it was he who'd tidied up his dad's maps for publication.
