[WANT] Tolkien's "Unfinished Tales" 2010 paperback

I have the complete set of the 2010 Harper Collins Tolkien paperbacks with the exception of Unfinished Tales. Unfortunatly this book has been reprinted with a new cover design but the same ISBN number, making it impossible for online retailers to sent me the correct edition.

I'm looking for [this edition with the Ted Nasmith illustration] (http://www.tolkienlibrary.com/press/images/Unfinished-Tales-PB.jpg) but so far have been sent this 2014 edition instead. .

I'd be willing to trade my brand new 2014 edition for someone's decent-condition 2010 copy.
