While working on the Dark Years project at Chuck Gammage Animation, I have really started to appreciate the early rubber-hose style animation, from the 30's and 40's. It is amazing the animation they could do then, with limited technology . Simple basic things that they were drawing, yes drawing! back then, that we have somehow evolved into a complicated and sterile process by using computers (more on that, and a perfect example over at Cartoon Brew).
Anyway here is a Betty Boop cartoon, and although it contains questionable material, is a very good example of what talented artists can draw.
See another Boop cartoon HERE.
