Clip art is a collection of pre-drawn images and illustrations that can be used in children's books to add visual interest and support storytelling. These images come in various styles, from simple line drawings to colorful animations, making them versatile for different age groups and themes. Authors and illustrators often use clip art to complement their narratives, making the text more engaging and accessible for young readers. The cost-effective nature of clip art also allows creators to enhance their works without the expense of custom illustrations.
