Book excerpt: "Compiled directly from The Jim Henson Company archives, Imagination Illustrated adapts the diary that Jim faithfully kept throughout his career, supplementing it with a trove of little-seen visual material, including rare sketches, personal and production photographs, storyboards, doodles, and much more. Throughout, archivist Karen Falk delves into the behind-the-scenes details of Henson's life and his artistic process"--P. [4] of cover.
