This is a 124 year old painting which was published in 1892 in a German magazine. If you observe the painting, you can spot two different animals in there? Can you say which one do you see? A rabbit or a duck?
According to a study in 1899 by a psycologist, if you instantly see both and switch between the two animal images, its proven that you have a more creative brain!
