This book is one of the main reasons why I wanted to become a illustrator. It would be great to make illustrations for children's books after this Columbia College thing. All the drawings are pencil and watercolor and I'm pretty sure that he hand-lettered the entire font. You can really get a feel for his style which is loose and relies heavily on line work and cross-hatching. What's great about his style of illustration is that it can be appreciated by all age groups. All the monsters are grotesque and kind of nightmarish. They are actually in fact caricatures based on Aunts and Uncles of Sendak who would come to weekly dinners at his house when he was a child. Most of his family were Polish-Jewish immigrants and because of their broken english and mannerisms they were the basis for the characters. He originally wanted the book to feature horses instead of monsters, but the only problem was he could not draw horses (I could not imagine what the story would have been like with horses.) When the book first released it was subject to some controversy and was even banned from a few libraries at first. It is really unlike any children's book. He plays on the darker, more mischievous side of a child's imagination.
