The heir to Jewish art dealer Alfred Flechtheim is pushing the German government for a decision on a pair of paintings by Paul Klee and Juan Gris that he claims were sold to Nazi collectors under duress.  Flechtheim’s great-nephew, Mike Hulton, claims that there is sufficient evidence to prove his claims, but he is currently being challenged by the Kunstsammlung Nordrhein-Westfalen.  ”We are asking for late justice. My aged stepmother Penny and I are very disappointed and somewhat puzzled — we hope this emotionally stressful and difficult situation will come to an end soon.” Hulton says.
