MUNICH.- The Staatliche Graphische Sammlung München has managed to secure as a long-term loan to Munich what is likely to be the most complete collection of Otto Dix’s prints anywhere in the world, amassed over several decades. The Greek collector George Economou, who has long placed German 20th century art at the heart of his overall collection, recently acquired this private collection of Dix’s works containing 526 sheets. In February of this year Economou entrusted the collection to the care of the Staatliche Graphische Sammlung München.
