Cohen’s book is out!

Rest is Up to You: A Boy Named Cohen Morano, 118 Artists, and a Watercolor Revolution
Like many kids, first-grader Cohen Morano likes to watercolor. What’s different about his paintings is that his father, Aye Jay, sends them out into the world to be added to and altered by a stellar roster of lowbrow artists, children’s illustrators, and street and graffiti artists. The resulting collaborations between Cohen and everyone from Gary Baseman to Shepard Fairey to Paul Frank form a stunning and playful body of work, with a focus on the creativity of childhood.
