This is a replica of the Marauder's map. It is based on the map of "Harry Potter and the Prisoner of Azkaban" but the castle shown is the one from "Harry Potter and the Goblet of Fire". It has several flaps to see different floors of Hogwarts and shows practically everything, from Hagrid's hut to the Black Lake.
