Bringing Home The Evergreens by Pauline Baynes who died on the first of August 2008.
I was very saddened to hear of the death of this wonderful illustrator, who painted such highly detailed, decorative, exquisite book illustrations. She was most famous for illustrating the Narnia novels for C S Lewis, she also painted many wonderful pieces in the style of Medieval Manuscripts. You can read about her life and work here.
