The artists of “Beyond Oz” invited visitors to travel over the rainbow with them: Climb a “Kansas Mountain” and ride a tractor. Ride a train or a riverboat. Kiss dragons good night and take a mud bath with frogs. Bike through the fields with Little Red Riding Hood and go to Diffendoofer School. Search for the alphabet in the world around you. It was the beginning of a wonderful, magical journey into the world of children’s books.
