BERLIN -- A German official is suggesting trying for an agreement with the reclusive collector of a massive trove of art which could allow some of the works to go on show to the public.

Authorities found more than 1,400 works of art at Cornelius Gurlitt's Munich apartment last year while investigating a tax case. Prosecutors are checking whether up to 590 pieces were seized by the Nazis, but plan to return works which belong indisputably to Gurlitt.

Bavaria's state justice minister, Winfried Bausback, was quoted Saturday as telling the Welt am Sonntag newspaper that negotiations could encompass restitution claims, secure storage for the works in future and "various models" under which some works could be shown publicly.
