Dora Maar au Chat presents the artist's most mysterious and challenging mistress regally posed three-quarter length in a large wooden chair with a small black cat perched behind her in both an amusing and menacing attitude. The faceted planes of her body and richly layered surface of brushstrokes impart a monumental and sculptural quality to this portrait. The painting is also remarkable for its brilliance of colour and the complex and dense patterning of the model's dress.
