This is kind of fun:

I didn't know until now that the original such Obama posters were made by ObeyGiant, an urban collective art project that's been around for twenty years or so. You have probably seen those creepy black, white and red "Obey" stickers pasted around cities.
The face in those stickers is wrestler/actor Andre the Giant, by the way. I can't say that I ever appreciated the whole "vandalism as art" thing. Now it seems to have gone a bit commercial and main$tream. And endorsing a presidential candidate? Doesn't seem very counter-culture to me. I wonder what ObeyGiant's positions on Social Security and free trade are.
