This book is fantastic. The artwork appears to be computer generated line art from actual stills and photographs from the TV series. So many of my favorite characters are included and there are also great depictions of King's Landing, Winterfell and Braavos. The book is also very large (11.5 x 11.6 inches), for comparison it is larger than Johanna Basford's books, Animorphia and the Daria Song books by about an inch on each side. The paper is a slightly off white, smooth light cardstock style. I only use colored pencils so I can't speak to whether markers would bleed through but the paper is very similar to the other better quality books I have. The pictures are printed on both sides of the page, with quite a few double page spreads. My only, only gripe is that with the double page spreads sometimes the subject is very close to the center (for instance in the picture of Daenerys with the Unsullied Army, Dany's shoulder is right in the crease). Very slightly annoying but the pictures are so great I'm more than willing to overlook that. The book also contains depictions of Ned Stark, Jon Snow, Arya Stark, Sansa Stark, Tyrion Lannister, Cersei Lannister, Jaime Lannister, Melisandre, Brienne, The Hound and Oberyn Martell and others, as well as castles, the Night's Watch, and the Night King with his army of White Walkers. If you are a fan of this series I couldn't recommend this book any more highly!
