This painting is a double portrait of two brothers, Josse and Gaston Bernheim-Jeune, who were art dealers in Paris. We see them in their gallery, with electric lights on the wall to illuminate the artworks. In the foreground, Gaston is sitting in a nonchalant way on the arm of a chair, while in the background, Josse is seated behind a desk. Neither one is looking at the artist, as if they were unaware of his presence as an observer.
