Each is part puzzle, part picture book. As a child fits the pieces together, detailed scenes emerge. Here's where adults can get involved, asking questions like "What do you think those children are doing?" Adults can also help identify objects in each museum. Art Day is full of famous works, like Vermeer's "Girl with a Pearl Earring" and Michelangelo's "David." Each puzzle is 48 pieces, finished size 24" x 18". Arrives in a shaped storage box. Ages 4 and up.
