A dreamlike anime illustration of Studio Ghibli depicting a large whale

A dreamlike anime illustration of Studio Ghibli depicting a large whale-shaped airship resembling a whale flying through the sky with fantastical mechanisms. This large wooden airship is equipped with a steam engine and wooden oar-like wings that mimic the pectoral fins of a whale, flapping to fly. This is a mechanical civilization, the Industrial Revolution, where functions of animals and unique machines are mixed together. This fleet is a merchant caravan, but there is only one flying aircraft carrier, and biplanes take off from the lower jaw of the whale. They always fly the same route at the same time.
