Writer Kelly Roman and illustrator Michael DeWeese adapted Sun Tzu‘s The Art of War into a graphic novel. To promote the comic book version of the famous military treatise, Roman and DeWeese had a doctor draw their blood in front of a live audience in New York City.

The blood was then used to stamp sample chapter-giveaways. Comics Alliance reports that clear tape was put on top of the blood for sanitary purposes. The curious can view this video about the event on YouTube.

According to an email sent by Roman, “the book integrates Sun Tzu’s iconic text into a story set 20 years in the future when China is the dominant economy and the financial industry is militarized.” HarperCollins’ Harper Perennial imprint will release the book on July 31st in trade paperback format.
