Looking at the images, it strangely appears as a modern second tier (ie. not NY or London), post-war western society. More industrial and progressive than I would have imagined.
The bulk of the USSR was much less developed. That photo of the miserable Дворец культуры (municipal culture center) is what most of provincial Russia looked like into the new millennium. That photo of the shop with relatively few goods available could have been taken in the twenty-first century in numerous provincial towns.
