Im npt going to lie, the Karelo-Finnish SSR is my favorite SSR, and though it was short lived, it lives forever in my heart
It so much is, like holy hell. You have like these extremely cool ones and then the Russian SFSR and Ukrainian SSR just plain suck.
The DPRK has a great emblem as well, I love it.
I made lemmygrad.ml/c/socialistemblems a while ago and then forgot about it until now, so that's cool, appreciate the reminder
