Almost microscopic exhibit 'Degas/Cassatt' plumbs artists' affinities and influences

In 1879, Edgar Degas made a charcoal and pastel image of two female figures, one standing with a book in her hands, the other seen from behind, leaning slightly on the staff of her closed umbrella. These are likely two visions of the artist Mary Cassatt, a friend, colleague and co-conspirator with Degas in Parisian impressionist circles.
