I'm not sure what point you're trying to make. If it's "DPRK is communist", you're not really doing that because nothing you mentioned has anything to do with communism.
For instance, I consider "Девушки фабричные" to have been a soviet trope (an image search reveals factory girls existed in the west as well, but don't seem to have been so frequently propagandised) and sure enough, here they are in the DPRK, even clasically at textile machines:

(among the machines I spotted on the site is a mask-making machine. Covid is a common denominator this year.)
