Normally when we draw we’re doing what’s called Additive Drawing; it’s adding charcoal, graphite, color pencils, or pen to a blank piece of paper. We draw, using an eraser as only an afterthought to remove mistakes or messiness. What if you turn that process on its head?
We found this article on The New York Times website about Leonardo’s famous drawings of strange faces. That also led us to this amazing looking show of his work at The Teylers Museum in Haarlem in The Netherlands.
