Mercer Mayer is considered one of the creators of the wordless picture form. A Boy, a Dg and a Frog was his very first published book and the start of the successful series about the adventurous little boy and his curious animal friends. Since then Mayer has gone on to create the classic There's a Nightmare in My Closet, the wildly popular Little Critter series, and many more beloved books for children.
