This is an anime illustration full of dreams, like that of Studio Ghibli, depicting a whale-shaped large airship that resembles a whale flying through the sky with a fantastic mechanism. This large wooden airship is a product of the Industrial Revolution, a mechanical civilization in which the functions of animals that fly by flapping their wings are mixed with the functions of machines themselves, such as a steam engine and wooden oars that imitate the pectoral fins of a whale.
