Van Gogh Museum Study Finds Artist Signed Only 15% of His Paintings
The Facts
On August 13, 2026, the Van Gogh Museum published the first extensive study of Vincent van Gogh's signatures, revealing that he signed only 133 of his 840 known paintings—approximately 15 percent. Researcher Julia Engelmayer collated all authentic signatures in a comprehensive dataset, published in the Van Gogh Museum Article 'Simply Vincent: An Overview of Van Gogh's Signed Paintings.' The study found that Van Gogh nearly always signed with his first name, as people outside the Netherlands struggled with his surname. His letters show that he considered most of his work practice or preparation, explaining why he never signed paintings before 1884 and why signatures decreased as his mental health deteriorated.
The Signal
The findings offer collectors and curators a new lens for authenticating and valuing Van Gogh's works, as signed pieces often correspond with paintings he deemed masterworks, such as 'The Potato Eaters' (1885) and 'Sunflowers' (1889). The study also highlights how signatures functioned as gifts, exchanges, or compositional elements—like the 'outrageous red signature' on 'Seascape near Les Saintes-Maries-de-la-Mer' (1888). For the market, unsigned late masterpieces from Saint-Rémy and Auvers may now be understood as reflections of diminished self-confidence rather than lesser quality, potentially shifting their appraisal.
