An artwork looted by Nazi forces from the well-known Goudstikker collection has resurfaced at the home of descendants of Hendrik Seyffardt, according to an art detective. The painting is a portrait by Dutch artist Toon Kelder, titled “Portrait of a Young Girl.” The detective, Arthur Brand, says the portrait had likely hung in the Seyffardt family home for decades, and he describes the case as unusually unusual. The reporting identifies Hendrik Seyffardt as one of the highest-ranking Dutch collaborators with the Nazis, and the discovery is therefore tied to the fate of property taken during the Nazi occupation. Both accounts describe the portrait as connected to the Goudstikker collection and present the finding as evidence that Nazi-era looted art can remain in private homes long after the war. The sources do not provide additional details about the circumstances of acquisition, the verification process beyond the detective’s assessment, or whether the work has been recovered by authorities or restituted.
