...Seriously? A map book? People are dying for the next one in the series and he blows time making a map book that won't even be out for two months?
Either the HBO series is sucking up all his time or he's slackin it. Not cool, brah. Hopefully Brian Sanderson's new Stormlight Archives doesn't suffer similar issues cause that series is gonna be amazing too.
1) George Martin had zero input in this project. He may be many things (glacially slow writer among them), but he's no visual artist or cartographer. That didn't stop him from claiming all the credit for it though. Nowhere on the cover is the artist's name - Jon Roberts - featured, and despite being called on it on his blog, Martin refuses to acknowledge that he didn't really do anything on this project.
2) Brandon Sanderson. Not Brian Sanderson. For someone so enthralled with his work, I would've thought you'd actually know his name. Brah.
Martin designed the world map (in a very rough way) and drew the rough versions of the maps, which Roberts then copied and went over professionally (as Roberts says on his blogs). Roberts's name is featured on the back cover. The title and GRRM's name is featured more prominently because that will make the book sell more.
