Ken Stott is a published author and an illustrator, who illustrated the Thomas mini books. He illustrated from the late 1980's to 1997. His pictures were basic and simple, using only one shade for each engine and black for the shadows. Despite this, Stott did include some aspects to the engines that kept it faithful to the Railway Series. One was Thomas' running plate, which remained straight, Henry with split windows on his cab sides and his running plate above the wheels completely.
