This Mark Dahle Portfolio includes a colorful abstract painting; twenty-five beautiful photographs of construction in Basel, Switzerland; and a children's story about a group of trolls moving to Norway. Unlike many picture books, the children's story is not related to the photographs in the portfolio. Children who are disappointed by this may draw their own pictures of hideous trolls on the pages if they like. From the story: When the trolls moved, they had to pass through a large forest. The trees and the trolls kept bumping into each other. It was no fault of the trees.
