The Heads of State designed this poster available for $40 on their website:
"As oil continues to leak in the Gulf of Mexico and the powers that be continue to seem, well, powerless, we all wait impatiently wishing we could do something—anything—to lend a hand.
We know this poster won't save the world, but we're hoping, with your help, it can make a small impact on the growing devastation.
We're donating half of the sale price of each Oil Drop poster sold (that's $20 per poster) to Oceana, the largest organization solely focused on protecting the world's oceans. Oceana has been awarded the exceptional rating of 4 stars by Charity Navigator, which means you can feel good knowing your money is having a direct impact."
