Every crook and every nanny of Hogwarts School of Witchcraft and Wizardry is noted on the Marauder's Map, from the classrooms and the halls to the secret passages that have been long forgotten. Seen in the films Harry Potter and the Prisoner of Azkaban and Harry Potter and the Half-Blood Prince, this is a detailed full-size replica of the Marauder's Map, printed on real parchment paper. Measuring 15 1/2' x 72' when open, the map folds down to 15 1/2' x 8 1/2'.
