The images seen here are from the recent book Witnessing the Robbing of the Jews by sociologist Sarah Gensburger. Gensburger explains in the text that the items pictured are Nazi-plundered treasures from Jews before and during the second world war.
The catalog was once stored in the German Federal Archives in Koblenz. The collection was organized post war by an art historian hired by the Allies in their attempt to return art stolen from the Jews by the Nazis.
Once taken by Nazi forces, these objects were counted, categorized and stored in Lévitan, a Paris department store. It was there that the Nazi occupiers of Paris prepared to redistribute the stolen goods to German citizens.
