As hard as I try to think an illustration idea about black and white for Illustration Friday, the one thing that keeps coming to mind is doing illustrations IN black & white (and grey) when I worked at newspapers. Most illustrations we did were not color, only black and white, and the challenge was to keeping it interesting without color. Incorporating maps, charts, headlines in the illustration. It was fun. I dug these up and to tell you how old they are - Adobe Illustrator 3.0.
