Self-portrait or Portrait of Theo van Gogh by Vincent van Gogh

Do you recognize the man in this portrait? There is still debate wether this is a self-portrait of Vincent himself, or if it's a painting of his younger brother Theo. Theo van Gogh was an art dealer, and Vincent's biggest supporter. The love and support from Theo and his wife, Johanna Bonger, is probably the most important reason as to why we can enjoy Vincent van Gogh's art today, as they both provided Vincent with financial support throughout his painting career, and made it their mission to get his art out to the world.
