portrait albrecht durer father national gallery authentic 1234772012

A new catalogue raisonné by scholar Christof Metzger argues that a painting in London's National Gallery, long considered a copy, is an authentic work by Albrecht Dürer. Metzger, a curator at Vienna's Albertina Museum, contends that the 1497 portrait of Dürer's father shows masterful technique that distinguishes it from known copies.
