Matt Groening created The Simpsons, but animator David Silverman gave them their iconic look. For years, Silverman hand-animated characters from the show, establishing the rules for their appearance that all future animators and merchandisers would follow.
As it turns out, Silverman is active on Twitter, and he recently unearthed a whole slew of sketches he made while drawing some of the earliest Simpsons episodes and commercials. Some of them are rough storyboards or concept sketches for characters, while others are early versions of scenes that made the final cut. They’re all quite neat and certain worth a look for Simpsons fans curious about how the sausage is made.
