Coloring by Age 4-5 / Easy to Learn

This series of four books introduces a new approach to children's comprehension of coloring. It provides convenient choices for the child, depending on his or her level of maturity. Each book contains illustrations whose features have been designed to suit the child's age. In effect, each book represents a certain level adapted to a particular age group. With each level, the lines of the drawings become more elaborate and more delicate.
