Book excerpt: Selected from the vast archives of the Walt Disney Company, this historic collection includes handwritten letters and notes of Walt's, rare character sketches from the 1930's and 1940's, replicas of Disneyland's opening-day tickets, photos, movie theater programs, comic strips, greeting cards, commissary menus, and other treasures, reproduced in facsimile form. Many of these special features are designed to be removable so readers can touch and hold masterfully reproduced bits of history. In addition, the book comes with a 60-minute CD that features previously unheard audio of Walt Disney , radio commercials from the 1950s, and never-before-released sound tracks from the parks' most popular attraction.
