An auction house in Europe is set to sell a painting by Gustav Klimt with an estimated value of at least 30 million euros. The portrait's subject, ownership, and provenance have been the subject of debate, adding to its intrigue. The painting's history, involving a wealthy Jewish family, the Nazi era, and subsequent ownership, has contributed to the interest in the sale. Various theories about the identity of the portrayed woman have emerged, each supported by different evidence. Legal agreements have been reached with the descendants of the original owners, settling the restitution issue, and gaining an export license. However, the actual identity of the subject remains inconclusive, with differing viewpoints from experts and legal successors. The painting's sale raises questions about its rightful ownership and the need for accurate research and legal opinions to identify the legal heirs. Despite these uncertainties, the auction will proceed without changes to the catalog, leaving the identity of the subject and the painting's history still open to interpretation.
