This is "Emile Bernard" by Henri de Toulouse-Lautrec, painted in 1886. What's striking about this portrait is the contrast between Bernard's reputation as a radical artist and how he's depicted here - more as a young bourgeois than a bold innovator. You can see why Lautrec might have portrayed him this way, given that they were classmates at Cormon's atelier in Paris.
Lautrec and Bernard had a mutually beneficial arrangement, where each would sit for the other to capture their likenesses. This portrait of Emile Bernard is one of twenty times he sat for Toulouse-Lautrc to paint him. The oil on canvas medium gives it a rich texture, don't you think?
