I'm in my 40s and have had more fun coloring pages from this collection than I thought possible. There are both simple and complex pages, good for all coloring abilities. There are plenty of images for girls and boys. There are also several Kobolds from 'Kobolds Ate My Baby' as well. If you play Munchkin or Apples to Apples, you are already familiar with John Kovalic's work. Plus, it's cheap and supports charity. What are you waiting for?
