The Renaissance Masters is filled with 25 historic paintings by 10 of the greatest painters of the era digitally restored and then grayscaled for you to color at home. Included in this book: Bottocelli, daVinci, Raphael, Michelangelo and more. **This book does contain some artistic nudity and violence but I do not feel that it warrants an adult rating given the context of classical art. I leave it up to you dear colorists to use your own discretion.
