Social awareness pieces

I've got a couple ideas for some recycling posters that I want to produce so I've been looking at some cause related pieces. These adverts by Felix Hornung for a homeless charity depicting animals without their shells show that nature is often a great source of inspiration. The campaign was apparently a storming success and the magazine similar to the Big Issue increased it sales massively overnight.

This is simply a fantastic use of typography to depict on going problems in Tibet..
Below are warzone images by McCann Erickson using human wounds as their canvas. The stitches are a harrowing comparison to trench lines.
