Look at this happy couple. Their baby has been baptized (into what we can't tell), they are happy and smiling. Family and friends look on. Welcome to Soviet propaganda pictures of the 1970s.
I'm a big fan of subtlety. There's no doubt in my mind that the above picture was taken in order to show to the capitalist West that things were just fine in the USSR. There's also no doubt in my mind that the people in the above picture are genuinely happy - they're not some pieces of Soviet propaganda machinery that were thrown in together at the last minute.
The picture above was sourced from a series of 1970s Soviet pictures here and here. I encourage you to check them out - they are really nice and quite inoffensive (even the military ones). That's what makes them so good for propaganda use.
These pictures were probably used in English language publications that the USSR sent out to Western Universities. I saw some of these in the university library in the late 1990s.
As you go through these pictures, look at what values they communicate. They communicate things like friendliness, ordinariness, happiness, progress, fun, intelligence, creativity, freedom, love. I wager that none of the shots taken were deliberately staged for propaganda purposes - but were exceptionally useful as propaganda nonetheless... which is why I appreciate them and the subtlety in doing so.
Looking through these pictures gives you the impression that the Soviet Union was, for a while, a true "workers paradise". Food is plentiful, work is enjoyable, progress is made and life is comfortable. Of course it was all a complete lie - the pictures don't show the seedy underbelly of drugs and prostitution and crime that existed even in places like the Soviet Union, nor do they show many pictures of non-Russian Soviets, or decaying infrastructure and the inefficiencies inherent in a bureaucratic and centralised command economy.
