Agatha Christie Mystery Collection edition in great condition. The front cover has some small dents and shelf-wear (see pictures), and the gold detailing on the front is a bit worn, but the rest of the book is crisp and clean. The Agatha Christie Mystery Collection (also known as the Agatha Christie Hardback Collection) is a book club set that was released by Bantam between 1983 and 2000. Typically, the volumes feature leatherette hardcover boards with gold lettered titles on the spine and a uniform silhouette of Christie and the series title on the front cover. The color of the boards is called “Sussex Blue”, which is a very dark navy that often looks black in certain lighting. The decorative endpapers for each volume were designed by Peggy Skycraft with book design by Barbara N. Cohen. Books are approximately 5.75″ x 8.75″.
