Told with poetic simplicity, this book shows how creative imagination - through the use of colour and imagery - can change the world from bad to good. With a box of coloured crayons and an eraser to rub things out, one child sets out to transform the world. By rubbing out 'hunger' and colouring in 'wheat', the world can be fed. By rubbing out 'crying' and colouring 'laughter', the world gets to sing, dance and be joyful. An unusual and deceptively simple picture book that imagines a world without discrimination, poverty or inequality.
