Swiss museum confirms authenticity of disputed Gauguin self-portrait

A Swiss museum has confirmed a Paul Gauguin self-portrait in its collection is authentic, refuting claims it was a forgery. The Kunstmuseum Basel's investigation, including pigment analysis and scans, found no evidence of forgery, though some areas were overpainted later. The painting, held by the museum since 1945, is now back on display and listed as a genuine Gauguin in a scholarly catalogue.
