The headline lot on sale is the 1944 hanging scroll ink painting, Garden Balsam and Butterflies, by Qi Baishi, who is considered "Picasso of Chinese art" and a forefather of modern Chinese painting.

Another noteworthy piece is a delightful Ming Dynasty (1368-1644) carving of Zhou Tanzi, a figure in Chinese folklore that represents filial piety. Zhou disguised himself as a deer to obtain milk for his aging parents - a story that's depicted in this beautifully carved dark jade creation that has an almost woodlike patina.

Other highlights include a range of wonderful rock-crystal scholar's objects - each complete with individuals stands - including an unusual Qing Dynasty (1644-1911) wrist rest.
