An accompanying catalogue to this exhibition reproduces the front and back of each of the 26 works and features original essays by celebrated Picasso biographer John Richardson and independent scholar Olivier Berggruen, the youngest son of Heinz Berggruen. John Berggruen is the eldest son of Heinz Berggruen. During his 90th year, Picasso executed the 26-page album over the course of nine days while at his home in Mougins, France, shifting his medium between pen-and-ink, pencil, ink wash and watercolor. The compositions vary in style and subject matter but most feature female nudes. Some of the works contain multiple female figures, while others combine a female nude with a still-life or male nudes. John Richardson has suggested that the album demonstrates references to the work of Ingres and Goya and that some of the female figures depict Picasso's wife, Jacqueline.
