At first you see a jumble of overlapping circles, but there's a picture hidden in there—keep coloring in the numbered circles, and you will soon see a lion, a tiger, a cheetah, or an adorable house cat or kitten. Querkles are a little like paint by number, a little like dot to dot, yet utterly unique—just use five colors that range from dark to light (or five different shades of one color) to fill in the numbered spaces and watch a dramatic image emerge. The book features 20 large pictures to color and a 19-inch double-page foldout.
