Get ready to play peek-a-boo - with a twist! Each unique board book in this set features six sturdy masks kids can hold up to their face and "try on." Perfect for imaginary play, little ones will have fun peeking through the die cut eye holes on each page to discover what they would look like as a cheetah with spots, a woolly sheep, a pup that's ready to go to sleep, and more! Includes 3 board books: Good Night Faces, Farm Faces, and Zoo Faces. Each measures 6-1/2 x 6-1/2". Designed for ages 8 months and up.
