This is my replica of the map to Erebor from the film "The Hobbit: An Unexpected Journey". This was originally drawn by Daniel Reeves for the film, modifying the one seen in Tolkien's book. Most notably, the designs for the mountain and Smaug is more artistic compared to the simplified Tolkien version, and Mirkwood has been renamed as Greenwood. An earlier version was also seen when Gandalf visits Bilbo in the prologue of The Fellowship of the Ring.
For this replica, I printed it on 165gsm watercolor paper through a laserjet, and then weathered the map with coffee, trying my best to also incorporate the folds and creases of the original prop. Once the weathering process is done, I used a cheap invisible ink pen and wrote down the moon runes. Under normal light, you wouldn't be able to see it, but under UV light it magically appears!
