The purpose of 3 Part Cards is to enrich and enlarge a child's vocabulary, and to aid in the classification of the environment. This is typically done with no more than 12-15 cards per set. The cards are meant to give a small introduction to the child by opening their minds so they are internally driven to find out more.Artwork included: Wood with Beech Trees, Self-Portrait, Evening at Weesperzijde Sun, Mill in the Evening, Windmill in the Gein, Mill in Sunlight: The Winkel Mill, The Red Tree
