A gold book, roughly the same size as a Jump Comics book. The cover is gold-plated aluminum-deposited paper, with gold leaf embossing. The endpapers are also gold. Furthermore, the top, bottom and fore-edge of the text are gold-plated (gold on three sides). The aim was to make the book look like a gold block by making the "gap" of hardcover books, which is usually 2-3 mm, as thin as possible. The binding was done by Oshima Itia, who also designed the exhibition logo and main visuals.
