If you read the New York Times blog “Abstract City,” then you know him by name. If you’ve ever looked at a cover of The New Yorker you’ve probably seen his work. And if you’ve done neither then perhaps you can at least appreciate when a bathroom is clearly marked “Men” or “Women;” If you do you share a fundamental principle with designer, illustrator and art director Christoph Niemann. Like a good comedian, Neimann’s deceptively simple designs have a way of presenting common knowledge in a new and interesting way. Of course, an intuitive sense of color and composition don’t hurt.
