Last night I finished Making Mischief: A Maurice Sendak Appreciation by Gregory Maguire. Its a fairly quick read and filled with a nice career overview of illustrations if you don't have the two large Sendak Monographs (which are fantastic). The book
compares various themes and influences/inspirations in his work and being more compact gives a good indication of the wide variety of styles and techniques Sendak used on various books.
Still have to see the Spike Jonez documentary that came out recently
