Ruth suggested that I look at a David Lowe cartoon, which I am hoping is the one pictured above (that features on the 'BBC bitesize' website).

They suggests that...

The cartoon shows:
Hitler and Stalin pretending to like each other.
Really they hate each other.
A figure (representing Poland) lying dead on the floor between Stalin and Hitler.
Both wear guns and military uniforms, and Germany's weapons (on the left) are in the background.
Dark clouds all around.

I will post further cartoons soon, followed by some expressionist work
