Amazon.com description: Product Description: "Designs in Nature" reproduced 100 color plates created by Ernst Haekel (1834-1919). In the main, these were drawings of animals, sea creatures and shells - most of them seldom seen outside biology textbooks or museum exhibits. The same 100 plates have been rendered in black and white to create "Designs in Nature: The Coloring Book". Each is produced at the same size as the colored version and on a separate sheet to make coloring and removal of individual images easier.
