Eagle-eyed Tiger & Bunny fans have spotted an Amazon pre-order page for a forthcoming three volume art book. Tiger & Bunny King of Works calls itself definitive, and it's hard to argue when it features the following:
Book I: The fine art concept materials for every character (printed on 10.12 × 14.33 in. paper, so you can examine in detail).
Book II: Complete script for every episode.
Book III: A selection of scenes (frames).
Tiger & Bunny King of Works will ship from Bandai Visual March 30th for 5,880 yen (a little over US $76). You get all that plus a specially-made calendar.
