A picture book is a type of children's book that features illustrations or pictures that are integral to the story. Typically, picture books are designed for young children, often preschoolers, and can range in length from a few pages to several dozen pages.
Picture books often have simple and easy-to-follow storylines, with a focus on visual storytelling. The illustrations may be colorful, whimsical, and engaging, and may convey emotions and ideas that are not expressed through the text alone. In fact, the illustrations in a picture book may be just as important as the words in telling the story.
