Aled Lewis, is a graphic design/illutrator from the UK with some very sharp skills. He has quite a few t-shirts printed at Threadless.com , so if you recognize his work here, It's probably from a shirt. I really love when i does really simple, minimalists designs, the message is killer.
He did this a few days ago. Via his tumblr he was encouraging people to donate to the red cross.
I am currently IN LOVE with this series of pictures.
