Franz Sedlacek, Twilight Song, 1931, Albertina Museum, Vienna, Austria.

Abstract art of a domestic scene. A living room at twilight. Against a far wall, a grandfather clock/stalky potted plant at one end and an electric organ/harmonium at the other. A humanoid figure that appears to resemble a dress form is seated at the keyboard. A broad-winged bat is flying in the middle of the room. Moonlight comes in through a single window.
