The latest batch of priceless artworks come from a trove discovered in a Munich flat in February 2012 which only came to light this month in a magazine
A task force appointed to research the origin of the more than 1,400 works found stashed in the home of 80-year-old Cornelius Gurlitt said in a statement that public prosecutors investigating the case had now posted a total of 219 of them on the website www.lostart.de.
It said all were suspected to have been looted or extorted by the Nazis from Jewish collectors. Pictures and titles have been published so that rightful owners can stake claims.
The task force has said about 590 of the works are believed to fall in this category and will eventually be put online.
Among the 101 artworks posted Thursday are "drawings, watercolours and prints by artists such as Edgard Degas, Eugene Delacroix, Paul Cezanne, Pablo Picasso, Albrecht Duerer and Honore Daumier," it said.
The Picasso sketch depicts Hercules slaying a centaur while the Cezanne is a drawing of fishermen on a riverbank. August Rodin is represented with a kneeling nude.
A Paul Gauguin pencil sketch of a woman, perhaps a Pacific Islander, can now also be seen as well as an Edouard Manet study of a woman.
Gurlitt is the son and heir of a powerful art dealer tasked by the Nazis with selling works that they stole, extorted or seized in exchange for hard currency, and with handpicking masterpieces for a "Fuehrer Museum" for Adolf Hitler in the Austrian city of Linz that was never built.
Customs police seized the works, including masterpieces by Picasso, Matisse and Chagall, during the raid last year on Gurlitt's Munich cluttered flat.
The authorities' reticence on the discovery of the long-lost works has drawn criticism from Jewish groups, including a much-publicized statement of outrage from the World Jewish Congress (WJC).
Last week, WJC President Ronald S. Lauder expressed astonishment at the German authorities. "They initially reported it as a tax avoidance scheme and not for what it really is - it really is someone having stolen Holocaust art and basically saying to the German government, 'Haha, I have it, you can't touch it'," he said.
