Lovely watercolours portray a great and diverse planet teeming with life at all times of day and night. People and animals of every shape, colour, size, and costume are seen, busy at work and play. As the yellow balloon floats through many time periods - ancient, medieval, and contemporary - and realms both natural and supernatural, young readers can also look for the small blue car, the fakir on his flying carpet, and the scoundrel in prison garb. This story will fascinate young readers as they embark on a lively and fun-filled journey around the globe.
