This is a Japanese (or English) language manga (comic) or a magazine featuring multiple manga series.
Shueisha's "Yu-Gi-Oh! Duel Monsters Valuable Book" series covers "Yu-Gi-Oh!" cards with color pictures of each card and information. This 10th volume catalogs new series cards, Asia version cards, structure decks, and limited cards, and also includes examples of deck composition, an explanation of the rules, and a card index. A King Mist card and a Fossil Dyna Pachycephalo card are included with this issue. Definitely a valuable book for "Yu-Gi-Oh" players! All text is in Japanese, with furigana for the kanji-impaired. Printed mostly in color. Softcover with dust jacket.
