This vintage hardcover is the official literary tie-in to the 1949 Metro-Goldwyn-Mayer Technicolor film Challenge to Lassie, which was based on the classic novel Greyfriars Bobby by Eleanor Atkinson. Published by Ward, Lock & Co., the book features 8 vibrant full-color plates and 80 black-and-white illustrations, including many film stills featuring the famous canine star. The story follows the legendary loyalty of a dog in Scotland, capturing the heart-warming themes that made Lassie a global cultural icon during the mid-20th century. The book is in fair vintage condition, with significant scuffing and edge wear to the pictorial boards, some fraying at the spine, and a small tear on the front cover. Internally, the pages show light toning consistent with age, but the color plates remain bright and the binding is intact.
