A painting by the Austrian artist Gustav Klimt that was considered lost for 100 years has sold for €30m (£26m) at an auction in Vienna.

Entitled Portrait of Fräulein Lieser, the unfinished picture was painted in the spring of 1917, when Klimt was one of the most celebrated portraitists in Europe, and a year before his death.
