the fifth decade (the 1940's)

Your task this week is to tell us about an invention, an artistic performance or production, a discovery, a building or a significant even that has nothing to do with WW2

You can add images or film clips to your submission and in 150 words or more tell us about this and its relevance - but remember that the key here is that have nothing at all to do with the war.

Make sure you cite your sources

Also - as per usual - this cannot be a US-centric story.

So: no US, no WW2
