I would like a drawing that is not exactly bitcoin related. Rather, it would picture a caricature of the difference between capitalism and communism. At least in my mind.
Both pictures would represent a circle of armed men, with a worker inside. The worker can do anything, for instance he can mine something (not bitcoins, the idea is that he has to be a symbol of labour).
In the communist version, guns are pointed inside the circle. Towards the worker, preventing him from escaping. And the worker has a unhappy face

In the capitalist version, guns are pointed outside the circle. They aim at protecting the worker's product of labour. The worker has a happy face.
No legend. I'll add it myself.
