ANTIQUES ROADSHOW rolls into Birmingham, where host Mark L. Walberg and appraiser John Buxton visit the Birmingham Museum of Art to look at a rare African wood carving from the late 19th century. Highlights include an autographed first edition copy of Harper Lee's To Kill a Mockingbird; a Titanic photograph and book tracing back to the owner's survivor relatives; and a Rolex military watch with ties to The Great Escape book and film that is appraised for $40,000 to $50, 000.
