BOOK OF HOURS A Tragic New York visual narrative told with 99 Wood Engravings. The Book of Hours takes us from September 10th 2001 until the morning of September 11th. We see the office workers as they go about an average day unaware of the history they will make and the life changing world that will follow. No words can describe the impact of such devastating transformation that day marks in our history. The world is now split into two timelines; the world before 911 and the world after.
