Jonathan Middleton produced over 2,500 publications in his career, mostly illustrated manuals for heavy trucks, cranes, aircraft components, engines, electronics, and radio-controlled vehicles. Although his work has been translated into six languages and copied across industries, his name is only on limited edition children's books or in short-run poetry collections. Two of his children's books have been published: "Grandpa McKutcheon's Kangaroomatic Rocking Chair" and "Two Turtles in the Rain" (in collaboration with Ponce De Leon Palmer). His next book is another collaboration.
