In "Portrait of a Young Girl," Cassatt posed her young model outdoors, probably at or near Château Beaufresne, the home the artist had purchased in the Oise River valley, about fifty miles northwest of Paris, in 1894. As in contemporary images of women and girls by William Merritt Chase, Frank W. Benson, and others, the girl appears immersed in nature and isolated from the outside world. The high vantage point, flattened space, and absence of a horizon, all suggesting the influence of Japanese art, are compositional devices that Cassatt also used in her color prints of the 1890s.
