Olof Sager-Nelson travelled to Paris in 1894, where he encountered French symbolism, that would influence him for the rest of his short life. Foster-Brothers depicts a boy and a young man in a twilight landscape. The boy is looking with a heavy gaze, while the young man is holding onto the boy and looking tenderly at him. Sager-Nelson devoted himself largely to figure paintings of this sort, calling them portraits morals, or “soul portraits”.
