This volume is the third in the Hilma af Klint Catalogue Raisonné series, focusing on The Blue Books created between 1906 and 1915. These books contain sketches and preparatory work that af Klint developed in anticipation of her significant "The Paintings for the Temple" series. Af Klint carried these sketchbooks with her during her travels, allowing her to share her artistic progress with friends in a more approachable manner.
