This is a remarkable example of Constrained Visual Language. It named Penguin vs. Batman. It is cleverly a single image can reveal dual layers effortlessly. The yellow portion of the poster shows the Tim Burton’s version of Oswald Cobblepot aka the Penguin. When we vertical flip, it’s the Dark Knight himself. I like this image and it use the Constrained Visual Language, it simple and clearly. We can easy to see the subject in this image.
