Irked by a tax dispute with Germany, Crown Prince Alois of Liechtenstein has canceled a planned loan of family-owned art to the Neue Pinakothek museum in Munich, Bloomberg News reported. Last month Prince Alois, right, called the methods employed by Germany to obtain information on tax evaders an “attack” on Liechtenstein, which punishes infringements on its banking secrecy. And a written statement from the prince’s office said, “All other approved loans for exhibitions in Germany will also be retracted.” The Neue Pinakothek exhibition “Viennese Biedermeier Painting From the Collection of the Prince of Liechtenstein” was to have run from May 21 to Sept. 21. “It’s a shame,” said Herbert Rott, the curator responsible for the show. “We hope we can reschedule it for a later date.”.
