Not affiliated with this seller in any way, just an interesting item for you Hobbit collectors. I just saw this on Ebay today:

From the auction description: "The Israeli airforce distributed copies of the book among its officers, accompanied by a letter from the Head of Personnel Dept. in the Air-Force command. This 1st edition copy still has the original letter inside."

It is one of the more interesting Hobbit translations out there (I think).
