The illustration on this puzzle comes from the pages of Neil Packer’s book ONE OF A KIND. In this story, a boy named Arvo explores the many ways in which we classify the world around us. The animal kingdom, modes of transport, musical instruments, art and architectural movements, cloud classification … anything and everything can be sorted into groups! In this image, Arvo thinks about himself in relation to other animals. If you are human, you are one of 7 billion other humans - but we are only a tiny part of the animal kingdom.
