The reclusive elderly man who stashed some 1,400 artworks in his Munich apartment for decades had about 60 more important pieces hidden away at his home in Salzburg, Austria.

Austria Press Agency (APA) reported Tuesday that works by the likes of Monet, Renoir and Picasso are among the newly discovered art found in the Salzburg home of Cornelius Gurlitt. His father, Hidebrand Gurlitt, is said to have dealt in "degenerate" art during the Nazi-era and research is underway to trace the provenance of the artworks.

German authorities discovered the hidden haul in Munich in 2012, causing a media sensation at the long-lost trove, estimated to be worth $1.35 billion.

Gurlitt's attorney, Christoph Edel, told APA that his client ordered the works to be secured and reviewed for any history as Nazi loot.

Whether Gurlitt will be able to retain any of the artworks is not known since a full list of the artworks and their histories of ownership has not yet been provided by the German government.
