Hmm… I like Kingpin's idea of an ‘art book’ like scrapbook. I think I can draw the pictures for that. It would take some time though :p with studing profiles and facial pictures.

As a proud owner of Xenogears: Perfect Works, which is, as I understand it, an art book in the broader sense, I would have to say a “scrap book” style section would fit right in.

Perfect Works had a huge amount of preproduction and behind the scenes art that the game was based on, and it also had sections detailing the politics and geography, science and timeline, of the Xenogears world. If they did that with Ghostbutsers, I'm sure it would be a fascinating book to read, and there would be plenty of development drawings to show us how they finalized the looks of the characters and such.

Oh, yes…lithographs. They're different than posters because of the process used to make them. They are much higher quality, printed on better paper (I suppose because lithography requires good paper to produce…I never got a chance to take a class in lithography), and usually have limited runs. Generally they'll have a 20/200 or some number written in the corner, to tell you which print in the run it is and how many prints are in the run. Lithographs are usually suitable for framing.

Oh, thank you for clearing that up for me.
