I'm glad that despite all these years it is still possible to find old anime from the pre-war era, and one of these anime is “Koukou Eisei/Dental Health” which was found a few days ago after more than 100 years. Apart from the educational theme of this film, I also liked the aesthetics that are characteristic for 1920s animations (for example, using distinctive elements in these animations or using elements from old Japanese paintings) I hope that in the near future it will still be possible to find old anime from that era, because they are important for its history which is partially lost
