One rainy night, Wally's family finds an old steamer trunk in the attic. Inside is a pile of paintings drawn from a single line from an enchanted pen. They could only belong to Uncle George, who believed that all stories begin with one line and a rich imagination. Award-winning author and illustrator Wallace Edwards explores the world of storytelling through a single pen line that grows into an image and the first line of a new story. Readers will be inspired to finish the simple stories that begin with "Once Upon a Line" or use the enchanted story line to tell their own unique tale. A key at the end of the book identifies the single line that is at the core of each image. An absorbing book filled with paintings rich in detail and color.
