A group of 17th century Dutch paintings, prints and other objects are coming to the Portland Art Museum from the Rijksmuseum. (If you haven't heard, most of the Rijksmuseum is closed for extensive renovations. So they are letting portions of their extensive collection tour the US and Japan.) I will only have to wait until 2007. Patience...
There will also be a small exibit of Dutch works from the Mauritshuis museum in The Hague coming this fall.
