This black and white image is of a giant bird with something (it looks like a poor woman screaming for help) in its beak.
When it is rotated, however, it is a man wearing a large hat and sitting in a boat, catching an enormous black fish.
This is a clever illusion. The bird’s eye becomes the fish’s and the small birds flying behind his head become ripples on the surface of the lake. The grass beneath his feet become leaves in the trees and his feathered body becomes the grass on the island.
