Antiques Roadshow: Las Vegas, Nevada - Hour One

At a Las Vegas magic theatre, host Mark L Walberg and appraiser Nicholas Lowery reveal that the artistry and value of vintage magic posters is no illusion. Appraisers at the Las Vegas Convention Center don't need sleight-of-hand techniques to pull amazing discoveries out of the crowd, including drawings by the legendary folk musician Woody Guthrie, an heirloom early-19th-century tavern clock, and a fabulous five-carat, Asscher-cut diamond ring, inherited from the owner's grandfather.
