Sotheby's has a new documentary series that can be viewed online. The first two segments - The Artist and The Collector - are availble through the link below. The third and forth segments are upcoming, with The Rostrum debuting October 11 and The House on October 18. Each segment is fairly short and light giving a little taste of each groups role, so to speak. Enjoy. http://yourartworld.sothebys.com/index.jsp
