The artwork is the same used in A Game For Swallows. The drawings are stark black and white. Each time the letter "o" is used in a word the author placed a dot inside it. This is a bullseye and shows how victimized the residents feel about the war. It is a most unconventional graphic style but works well for the story the author is telling.
I loved the book but must admit "Swallows" is better.
