If you click here you can see a series of old black and white photographs converted to colour. For me particularly noteworthy is the thumbnail image on the left of Joseph Goebbels scowling at photographer Alfred Eisenstaedt after finding out he’s Jewish in 1933. Have a look and see what you think.
This link takes you to a diagrammatic representation of the relative power of the great states since 2000BC. It shows the ebb and flow of power well, but the later stuff does feel rather western. There is no insight into how the judgements were made. I would be interested to know what you think.
