In Tulsa, Oklahoma, ANTIQUES ROADSHOW host Mark L. Walberg joins appraiser Eric Silver at the Philbrook Museum of Art to look at seemingly everyday housewares, appliances and electronics that were transformed into stunning functional art by 20th- century industrial designers. Highlights include an 1826 English gadget cane, equipped with both a pistol and a telescope; a vibrant 1931 Oscar Mayer in-store display; and a circa 1600 Ming Dynasty cast bronze guardian figure, valued at $70,000-$100,000.
