Overview

• Algemeen Dagblad reporters found Giuseppe Ghislandi’s Portrait of a Lady in photos from a Mar del Plata real-estate listing and sent the images to the Dutch Cultural Heritage Agency.
• Agency researchers judged the work consistent with the long-missing Goudstikker painting but said definitive authentication requires inspecting labels or marks on the back.
• The listing tied the home to descendants of Friedrich Kadgien, a senior aide to Hermann Göring who fled to South America, and the photos were subsequently removed.
• Goudstikker heir Marei von Saher has retained U.S. counsel and plans a formal restitution claim to recover the portrait.
• Interpol and the Argentine Federal Police are now involved to locate the painting and prevent it from being moved, as investigators also flagged a possible Mignon still life in related social media posts.
