Kara Walker sugarcoats nothing. Her masterpiece public art commission, A Subtlety, 2014, was a 35-foot high racial confrontation of artifact, mythology and American history in the form of a sphinx packed from 80-tonnes of Domino white sugar crystals. Walker's practice first caught audiences with her haunting paper cutout silhouettes retelling the injustices of slavery and the foundations of American capitalist culture.

Walker's immense talent matched by her cunning commentary has made her one of the most important contemporary artists today, having enjoyed major exhibitions at the Walker Art Center, Minneapolis and the Whitney Museum of Art, New York in addition to permanent placements within the collections of the Metropolitan Museum of Art and Art Institute Chicago. Her auction market is strong for a mid-career artist, with works reaching more than $300,000.
