VS Historical Animation

My company has the division to make visual contents. It made recently a DVD collection for the histroy of animation films in the world. I watched it.
The works are very old, made in 1920's or 30's. For example, Walt Disney's very early works are in the collection. They were the ones before Micky Mouse. Young Disney's works were very different from the ones we know as Disney animation. The most famous one was Alice series, in which a young real girl "Alice" acted with animation characters. Real film and animation were combined.
The works of Max and Dave Fleischer II were also impressive. A character they made are a very famous one. Betty Boop is it. Japanese calls it Betty-chan.
Watching some old mono-tone Betty series, I thought they were certainly unique. Even though the animation was for kids and the stories' themes were adventure, friendship or thriller for instance, the existence of Betty reminds us of sexuality. So, I guess that Betty was very exciting for the kids in early 20 centuries.
Very very early animations in 1910's were also interesting and exciting. The oldest clay animation by Willis O'Brien "Swat the fly" was very short (about 3 minutes) but the impact was strong. It enlarged the possibility of expression in animation. And, he made many films of prehistorical story, especially about dinosaurs. Their moving in his films was very realistic. Therefore, his skill of animation-making created one of the most famous monster character, King Kong later.

I sometimes drew pictures on the rims of a textbook in my school days, and made animations. The works would be historical in the future.
