If you don’t know what Flag Stories is, it’s a lost media flag series that tells the story of a country’s flag. Although it’s a French cartoon, the official language of this series is English. 51 episodes have been made, however, nine episodes have been found: the United States, Canada, Brazil, South Africa, the United Kingdom, France, South Korea, Japan, and Australia. The other 42 episodes have yet to be found. These are the flags that appear in the intro, which can be seen from 0:01-0:15 in this video of the United States episode: https://www.youtube.com/watch?v=IysQohrXWzs.
