When Mercer Mayer was a young artist looking for book illustration work, a potential employer suggested he give up and throw away his portfolio. Fortunately for the thousands of children who have enjoyed his many books, he did not give up. Indeed, he went on to create one of the first widely-published wordless books for children, A Boy, A Frog, and a Dog. That book and its successors were hugely popular.
Soon after that, Mayer tackled one of the biggest problems facing young children—how to cope with fears of the unknown. Rather than write pedantic, matter-of-fact, non-fiction children’s books, he turned the process of dealing with those fears into engaging stories from a child’s point of view: There’s a Nightmare in My Closet; There’s an Alligator under My Bed; and There’s Something in My Attic.
