The final evening of Sotheby’s Penthouse Lounge on 1 December celebrated the new and the innovative. A special invitation was extended to young collectors, who picked up iPads to browse the offerings in nine upcoming Sotheby’s online sales including, Exceptional Exposures, 20th Century Photographs Online and IfOnly Presents: The Experiences Auction. Sotheby's experts were on hand to explain the new platform and assist people in the registration process. Click ahead for images from Sotheby’s at Soho Beach House.
