Hans Bunde originally created Penguin in 1954, one for each of his sisters. Penguin is available in two sizes, small and large, and it is made of beech wood. The hand-painted back represents the silky feathers of the bird, and the chest is left unpainted to represent the white bellies penguins are well-known for. Although extremely simple, Penguin is designed in a way that no one could mistake it for another species.
