Antiques Roadshow

Philadelphia, Pa - Hour 2

Host Mark L. Walberg visits the Philadelphia shop and museum of appraiser Fred Oster to view his impressive collection of instruments and learn more about the city's long history as a center for musical instrument makers. At the Pennsylvania Convention Center, experts orchestrate a symphony of appraisals, including a very valuable Alexander Calder maquette (scale model) for a large sculpture commissioned for the 1958 Brussels Worlds Fair; a stunning collection of Camera Work magazines, published in the early 20th century by renowned American photographer Alfred Stieglitz to promote the idea of photography as art; and a very rare handcrafted chair by master Arts and Crafts furniture maker Charles Rohlf, passed down from the owner's grandparents and estimated to be worth $80,000 to $120,000.
