Stuart Tresilian 

Is a British illustrator who worked on many children's books including Rudyard Kipling's Animal Stories and All the Mowgli Stories.  He lived from 1891 to 1974 and later on in life became an art teacher. He was very well known for his work in book illustration. His work for Kipling's books are black and white. They are very textured, made up of many lines, normally vertical. His work reminds me of the work of Sergio Toppi. I really like this style and his use of composition. He normally breaks up his illustrations within the book pages and the artwork doesn't look as stagnant, it almost interacts with the text. His drawings are very atmospheric and moody and they set the tone for a more adult oriented novel, not one of a children's book. Of course, these drawings were made a long time ago and having illustrations in the first place made it constitute as more of a children book, less geared towards adults.
