This licensed Hogwarts Castle lamp is a Bradford Exchange exclusive. It’s also limited edition and comes with a certificate of authenticity.
The lamp features a hand-painted Hogwarts Castle, illuminated from the inside, on a mahogany base with a Marauder’s Map lampshade.
It’s neat that there are both lights in the base and up top in the shade, and you can turn on either or both. For instance, you can only illuminate the castle for a dim nightlight. And because the map is printed inside the shade, it’s more or less hidden when the top bulb is off.
