We recently added some great new Banksy Cards to Cool Cards.
In a similar vein, enjoy these Adbuster spoof adverts.
Who are Adbusters? "We are a global network of culture jammers and creatives working to change the way information flows, the way corporations wield power, and the way meaning is produced in our society."
"Culture Jammers" ? A great example of 'culture jamming' would be The Yes Men.
The Yes Men: "Impersonating big-time criminals in order to publicly humiliate them. Our targets are leaders and big corporations who put profits ahead of everything else."
