A true heroine of modern art, Niki de Saint-Phalle (France, 1930-USA, 2002) gave birth to a complex and unique universe which she fed with autobiographical, cultural and political references, synthesis between life and art. The story of Niki de Saint Phalle is that of an artist on a quest for emancipation in a world dominated by men. Her highly individual stance and her profoundly innovative oeuvre left a firm imprint on the cultural landscape of the 20th century. This book, published for the retrospective of Niki de Saint Phalle hosted by the Guggenheim Museum Bilbao, explores numerous aspects of a unique, heterogeneous, and complex oeuvre, and follows the artist's voice through the texts she wrote herself, of irreplaceable value for an understanding of the sense and dimension of her work. This volume provides a unique opportunity to explore a career marked by metamorphosis and constant reinvention; the works on display range from the paintings with objects of 1958-59 to a group of large sculptures conceived in 2000, two years before the artist's death.
