Joan Mitchell becomes most expensive female artist at auction in Asia with US$17.6m Sotheby's sale

Joan Mitchell’s diptych "La Grande Vallée VII" sold for HK$137 million (US$17.6 million) at Sotheby’s Hong Kong, setting a new record for the most expensive work by a female artist ever sold at auction in Asia. The 1983 masterpiece, part of a celebrated 21-painting cycle dedicated to a grieving friend, led a successful Modern and Contemporary Evening Auction that saw a 100% sell-through rate for its 54 lots. Other notable results included a Mark Rothko canvas that more than doubled its low estimate and significant sales for works by Sanyu and Zao Wou-Ki.
