Another quality Ebay item, with a very unusual signature but I suppose it is what you should expect from someone who dies 16 years before they signed the book. ... ZWDVWQQrdZ1QQcmdZViewItem

The usual request please report to Ebay, they only seem to do anything about these if a few people complain.

EDIT: I looked at it again and it could be signed by John Tolkien I suppose in which case it may be genuine, are examples of his signature anywhere on the Internet to compare with, I only have examples of Christopher and Michael's signature.
