I recently acquired a first printing of the Unwin Hyman edition of The Annotated Hobbit. There is some information on Tolkienbooks.net and Tolkienbooks.us that indicates there were only 1,500 copies printed for the Canadian market (where I am located).
I don't seem to be able to find another Unwin Hyman edition for sale online (all appear to be Houghton Mifflin).
Would the (relatively) reduced print run explain this? Thanks in advance.
