The painting is called La Petite Niçoise (The Small Girl from Nice) and is an oil on canvas painting by Berthe Morisot, executed in 1889. It has been in the collection of the Musée des Beaux-Arts de Lyon since 1907.
The painting shows a young girl presented at the waist, seated and turned three-quarters. She stares at the viewer with her brown eyes, her hands resting one on the other at the level of her knees. With her long brown hair in the wind, she wears a discreet earring in her left ear (the only one visible), lipstick, a dark blue top decorated with a rose in the buttonhole and a green-hued skirt. Behind her unfolds a barely sketched mountainous landscape, with a few sketchy forms of trees being recognizable on the left.
