Messrs. Moony, Wormtail, Padfoot and Prongs are proud to present The Marauder's Map! Tap the wand on "I solemnly swear that I am up to no good" to begin the fun! But before you see Harry, Ron, Hermione, Snape, and Dumbledore walking, improve your knowledge of magical artifacts featured in the British Library's exhibition "Harry Potter: A History of Magic." This carefully curated collection will help you explore the magic at the heart of the Hogwarts School of Witchcraft and Wizardry's curriculum. When you need a break from your "studies", enjoy a Chocolate Frog while putting together a jigsaw of Flying Keys. You better bid quickly! There are lots of Potterheads out there!
