Overview

• The painting, identified as Portrait of a Woman (also reported as Portrait of a Lady) by Giuseppe Ghislandi, was visible above a sofa in a Mar del Plata villa listed by Robles Casas & Campos.
• Reporters traced the property to descendants of Friedrich Kadgien, a financial adviser to Hermann Goering who fled to South America after World War II.
• Advisers to the Cultural Heritage Agency of the Netherlands say authenticity appears likely based on images and dimensions, though definitive provenance requires examining back-of-canvas labels or marks.
• Heir Marei von Saher says she will file a claim to recover the work and has engaged an American lawyer to pursue the case.
• Researchers are also probing social-media posts that may show a missing Abraham Mignon still life linked to the Kadgien family, as prior Dutch actions returned more than 200 Goudstikker works after a 2006 review.
