From AdFreak:
People in Chicago must be starving after the long, cold winter there, as they have ravaged this bus-shelter ad from ampm convenience stores to retrieve the snacks inside. Ogilvy put the ad up with the idea of slowly taking the snacks away over a four-week period, to reveal the tagline, “Too much good stuff.” Area vandals shortened the campaign’s run to two days. Curiously, they didn’t seem to like the Doritos much.
