An encyclopedia of 384 pages, with a hardcover and relatively good quality paper inside. It includes all the favorite DC heroes, in alphabetical order, with basic information about each character (personal details, alliances, enemies, etc.), and mini historical descriptions from the archive. At the end of the book, there are also references to lesser-known characters. It is suitable for almost all ages (my son is 6+ and he reads it for hours). A "necessary" addition to every fan's library of the genre. Attention, it is not a comic book!
