Monster at End of Book Little Golden Book

Many adults name this book as their favorite Little Golden Book. Generations of kids have interacted with lovable, furry old Grover as he begs the reader not to turn the page--for fear of a monster at the end of the book. Oh, I am so embarrassed, he says on the last page . . . for, of course, the monster is Grover himself! Ages 3 years and up.
