From a private collection. I have several other Agatha Christie titles available but I sorted them by publishers and cover design because that’s how I organize my own library collection. Books range from very good to acceptable but believe it or not NO markings whatsoever on any copy not even names penciled on the inside cover! These are mostly 1979 and a few 1980 Great for your own collection or to resell. I also do bulk shipping if you are interested in my other titles available.. 13 at Dinner Murder in Mesopotamia Poirot Loses a Client The Man in the Brown Suit Murder on the Links Cards in the Table N or M?
