French photographer Claudine Doury began going to the Artek "pioneer camp" in the summer of 1994, two years after the end of the USSR. But, as the French say, “Plus ça change, plus c'est la même chose".
Aleksandr Ranchukov (1943-2019) was a photographer from Kiev, Ukraine, who earned a living as an architectural photographer in the USSR but also took street photos in his off hours. Those became his focus from the mid-1990's.
Judging from clothing, this looks to be from the late 1970's-early 1980's. A crowd has gathered around a spaceship.
I am trying to ID the above car. It's from the early 1970's Pontiac Bonneville/Catalina/Oldsmobile Delta 88 family. Those were ~ 5.7m in length. A typical Soviet Lada was ~ 4.1M. There was a very famous Soviet film, "An Office Romance", where the male lead gets inside Volga 24 and says to its owner, "Wow, this feels like a house". And Volga 24 was 4.7M, a modern Honda Accord.
It looks like a diner/restaurant in the late 80's, maybe even early 90's. The cone shape glass containers on the left is how the Soviets sold fruit juices. From the haircuts, the customers are probably foreign tourists. The lady in a nurse's uniform is a service clerk/waiter.
