Watch Antiques Roadshow Season 7 Episode 9 Online

A three-week sojourn in Cleveland concludes. Items appraised range from a 1940 Roy Rogers movie poster (for “Young Buffalo Bill”) to a Jacobean-style cupboard that was once owned by Ohio politico Mark Hanna, the “President maker” behind William McKinley. Then there's an item a woman bought for 50 cents. “We didn't know what it was,” she admits to host Dan Elias. It turns out to be a clock to time racing homing pigeons, and it dates from 1902. Elias also visits Cleveland's Crawford Auto-Aviation Museum (Cleveland rivaled Detroit as an early automotive center), and appraisers Leigh and Leslie Keno trace the history of the Chevrolet Corvette.
