I'll leave you all with some great posters from artists and designers supporting the Haiti Poster Project:
"THE HAITI POSTER PROJECT was launched three days after the January 12th, 2010 earthquake in Haiti. The project is a collaborative effort by the design community to help effect change through our work. Signed and numbered, limited edition posters have been donated by designers and artists from around the world. All money raised will be donated to Doctors Without Borders."
