David Norman, Chairman of Sotheby’s Impressionist and Modern Art Department Worldwide, summarised the importance of the composition."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 dazzling portrait. The painting is also remarkable for its brilliance of color and the complex and dense patterning of the model’s dress. The powerful figure is set in a dramatic, yet simple setting composed of a vertiginously inclined plane of wooden floorboards and shallow interior space that is arranged in a manner reminiscent of Picasso’s earliest manipulations of space in a Cubist manner.
