This non-fiction picture book tells the story of the invention of Crayola crayons. Crayons are such a ubiquitous part of childhood, it’s fun to hear the back story of how they came to be. This is a great way to introduce children to non-fiction connected to something they are all familiar with. The illustrations are colorful and inviting and help set the stage for the turn of the twentieth century, when this childhood toy came into being.
