It's the unforgettable phrase that activates the Marauder's Map, immortalised here as a stunning poster. The Marauder's Map, of course, is the magical parchment that reveals every detail of Hogwarts — and everyone in it. But the map won't divulge those secrets to any ol' wizard. Instead, the map will remain blank — or just choose to insult you — until you utter the magic words.
Created by celebrated illustrator Ahoy There exclusively for Pottermore, this piece epitomizes the artist's flair for dynamic design and detail.
This poster is offered on the occasion of the exhibition Harry Potter: A History of Magic at the New-York Historical Society. The exhibition captures the wizarding traditions of folklore and magic at the heart of the Harry Potter stories through centuries-old treasures including rare books, manuscripts, and magical objects from the collections of the British Library and New-York Historical Society—with original material from Harry Potter publisher Scholastic and J.K. Rowling’s own archives.
