Antiques Roadshow (US)

Appraised at the Tulsa Convention Center: a desk used in Congress in the 1850s (and found by its owner in a chicken coop); a handwritten diary kept by delegates to the Oklahoma Constitutional Convention in 1906-7; and memorabilia from a Wild West show that includes a poster for a documentary in which an unknown cowboy named Tom Mix made his screen debut. Also: host Dan Elias presents a quickie survey of Tulsa's art-deco architecture.
