The Stedelijk Museum in Amsterdam, a museum of modern and contemporary art, is hosting an extraordinary exhibit of works from its own collection. However, the question is, does the museum really own the works? During the Nazi occupation of the Netherlands (from May 1940), the director of the Stedelijk accepted works of art for safe-keeping from Jewish owners. This exhibit, “The Stedelijk Museum on the Second World War,”
includes facsimiles of provenance records from that period with the hope that original owners may be identified. This article by Mary M. Lane from the online Wall Street Journal (2/27/15) includes photographs of the bunker in the dunes of Castricum, a Dutch seaside town, where many artworks were stored during WWII.
