Expressions of Emotion: Four Heads from Diderot's Encyclopédie

An etched plate of four numbered studies of human heads in varied expressions, rendered in fine hatched line on cream paper. Two figures show a child-like face with tousled hair and a bearded, scowling older man in a wrapped turban; two lower heads show a grimacing man and a downcast young woman with a veil.
