Akira Club

From Dark Horse Site - "Katsuhiro Otomo's epic manga, Akira, is considered by many to be the finest work of graphic fiction ever created, a work of astonishing power and visionary scope, and possessing a level of illustration skill unmatched in the annals of the medium. Now available for the first time in an English-language edition, Akira Club is an essential companion to Akira, a dazzling collection of Otomo's mind-blowing visions, including over one hundred title-page illustrations created for the original serialization but not included with the published collections of Akira. The book also features rarely seen alternate art, preliminary drawings, production sketches, and a variety of Akira posters, advertisements, and products, all accompanied by fascinating commentary by the artist himself. No Akira enthusiast, manga fan, or devotee of fantasy and science-fiction illustration should be without Akira Club."

The original Japanese Akira Club Book was published by Kodansha in 1995. 3500 yen (ISBN-10: 4-06330-003-X). I believe it is now out of print. It was released in English in 2007 and should be readily available.
