Franz Marc (1880-1916) was one of the most important members of the Blue Rider group of painters, together with artists such as Wassily Kandinsky, Gabriele Munter, August Macke, Paul Klee, and Alfred Kubin. The group marked the high point of German Expressionism and had a profound influence on international art during the brief period from its formation to the start of the First World War. The third and final volume of the catalogue raisonne contains the thirty-two sketchbooks by the artist and illustrates the hundreds of drawings he made from life as studies for works in other media. Over one thousand sketchbook pages are catalogued and reproduced for the first time, many of which had been separated from the sketchbooks and are here re-united with details of provenance and present location to provide a complete picture of the artist's preparatory work. The volume also contains detailed entries and illustrations of the artist's forty-five prints, including information on media, provenance, and location. It begins with introductory texts that explain the authors' methodology in cataloging the work and concludes with concordances, a glossary of terms, bibliography, and index.
