Anti-Bus ad on a Bus, originally uploaded by FAILocracy.

I designed this advertisement by request for an organization that was opposing an expansion of the public transit system in Grand Rapids Michigan (after discovering that it would be cheaper and more fuel-efficient to just give all the riders free cab rides).

The creators of the campaign wanted to put the ad on a billboard, but the billboard company rejected the ad as disparaging. But, when they submitted the ad to appear on the bus itself, free speech and fairness regulations forced them to accept it.
