ATLANTA — Atlanta’s High Museum of Art is inviting visitors into a colorful world populated by playful animals and imaginative children. “I See a Story: The Art of Eric Carle” opens today and features more than 80 collages from 16 books by the author of children’s favorites like “The Very Hungry Caterpillar” and “The Grouchy Ladybug.” Carle’s bright images explore themes including childhood, nature and journeys. Adults can revel in the nostalgia of books they read as children or read to their own children, while kids are treated to an exhibition arranged with them in mind.
