That's not why the good doctor's drawings are important, though. Not for making me a cartoonist. They're important because in their spareness they leave room for our own imaginations to be a participant in their foolishness. We fill in the details in our minds. Sometimes with that part of our mind that is dangerously close to a state of atrophy.
Children usually draw with abandon.
They almost spontaneously erupt with artistic expression as soon as they learn that their little hands can actually create. They put down their crayons and, if they're lucky, find another way to express that side of their personality. Yet even after their solemnly matured brain's right side has shrunk to the proportion of a Florida chad, Dr. Seuss' artwork can evoke a dimpled grin out of them. Seems to me that Dr. Seuss' works are just about perfect exactly as he produced them. They don't need to be colorized, airbrushed, animated or live-actioned.
