Duolingo's Yiddish flag for their newly unveiled course
from /r/vexillology Top comment: The flag is just a stylized "אָ" (Yiddish leter o) on a blue background. Based on [this](https://forum.duolingo.com/comment/36741759/Flag-for-Yiddish) Duolingo blog post it seems the course developers had been planning on not using the "popular"[black and white Yiddish flag](https://assets.forwardcdn.com/images/cropped/yiddish-flag-1434390996.png) design for quite some time.
