Storyboard of FLCL (or FLCL Storyboard Collection) is a 2005 artbook that contains the complete storyboards for all six episodes of the original FLCL, which amounts to a total of 880 pages. The book features a few illustrations of characters in between episode storyboard, as well as a bonus storyboard for the ending cinematic, and a comment from the pillows.
It should be noted that the storyboards themselves vary from basic scribbles to very detailed drawings, as is the storyboard process in animation. Furthermore, there are often brief notes on a few pages giving more insight on the current storyboard being viewed such as the thought process behind and which artist drew the storyboard.
