This distinguished volume of Robinson's art covers the breadth of his comic work, from his early musings on the state of British industries and his very first inventions, to the mocking, anti-German propaganda created during the First World War, and final sketches of the Second, during which he died. ''Contraptions'' is a definitive collection that will enchant future generations for as long as machines remain machines and human beings need reminding that that is all they will ever be.
