Working closely with Martin, the artist has been commissioned to illustrate an assortment of castles from the series for the upcoming ASOIAF sourcebook . There will be 13 works produced, each a distinct location based on the author's descriptions.
The artwork looks fantastic, so follow the link if you want to see those beautiful paintings!
I have a feeling that these illustrations will whet ASOIAF fans' appetite for that sourcebook. . .;-) It sure looks like this will be a 100 times better than The Wheel of Time sourcebook which was published a few years back.
