A Gustav Klimt painting, “Litzlberg am Attersee,” looted by the Nazis from a Jewish family, will be returned to its rightful heir in Canada.

Currently owned by Salzburg’s modern art museum, MdM Salzburg, the painting is estimated to be worth as much as €30 million (£26 million).

Georges Jorisch, an 83-year-old retired Montreal camera shop manager, says the Klimt was seized by Gestapo from his grandmother's home outside Vienna. Amalie Redlich was deported to Poland where she was killed.

Jorisch and his father had left Vienna in 1938. When they returned later, Redlich's art collection was gone.

In 2010, another painting owned by Jorisch's grandmother, the "Church of Cassone-Landscape with Cypresses" was sold at Sotheby's for $45.4 million.
