Vintage painting "Portrait of a girl in a school uniform". The author - French artist Jean Billon, has been exhibited at various auctions in France and the United States. The painting shows a girl in a school uniform with her hair neatly pulled back, looking at the viewer with a half smile. As in many of his works, Jean Billon depicts the model against a bright monochrome background to focus the viewer's attention on the girl's individual traits. Canvas, gouache. France, 1950s.
