In 2012 I was commissioned to illustrate the official maps of Westeros and Essos for the world of Game of Thrones. Each map is 3 feet by 2 feet in size, 72 square feet of maps in total, and they're sold as a 12 map folio called the Lands of Ice and Fire.
There's a bunch of articles on my site about the process behind the maps, as well as some detail shots. The maps are all © George RR Martin, 2012, used with permission
Warning – the last map contains spoilers as it shows the character journeys up to the end of A Dance With Dragons.
