Soviet Propaganda Posters: Capital by Viktor Deni, 1919.

Picture caption from the website:

Capital as the source of all evil. Under the image a satirical poem by Demjan Bedny. The red text on the left states that damaging the poster or pasting another one over it is a counter-revolutionary crime.

This is just one of many very interesting collection of Soviet, Chinese, and Cuban propaganda posters maintained by the International Instutite of Social History.
