'Cold War' set

I saw this 'cold war' chess set on eBay, for very little. It didn't come with a board, but I felt it would fit well on the board that came with my pseudo-italfama set.

The pieces are made of wood, and painted in the colours and symbols of the Soviet Union and the United States.

All I could find on the internet on this set suggests it may date from the 1950s, which would make sense from a 'cold war' perspective. 

If anyone reading this knows a bit more about its history, please let me know!
