Decorative cover from 'Saturn and its system' by Richard A Proctor (1837-1888), published in London in 1865. The development of publishers' book bindings in the late nineteenth century led to a huge increase of bright, decorative covers for popular science and technology books. Most were unsigned by artists employed by the publishers. This example in blue publishers' cloth shows Saturn and its rings blocked in gold.
