The  character in the top window of this downtown building is Gaston Lagaffe, another well-know European comic character. This sort of whimsy is all over town during festival week. And year-round in Angouleme, for that matter. Gaston is singing, and his neighbor in the window below is complaining. (Update: Friedrich writes, Gaston isn't singing, he is playing his self-constructed Gastophone. Thanks! -- JJ)
