Leo Lionni's playful mice present the three most basic early-learning concepts in one irresistible board book. Cheerful collage mice prance across the pages as they identify the colors of the rainbow. They make math fun by counting each other. And they're up to their best tricks as they cavort, juggle and play hide-and-seek with the 26 letters of the alphabet. With its rounded corners and non-toxic ink, Colors, Numbers, Letters can be enjoyed by the very youngest of "readers." It's brimful of fun things for parents to point out and talk about with their baby or toddler, and makes an inexpensive, yet beautiful and thoughtful gift for baby showers.
