And now Twitter user AustinHorse alerted me to an interesting advertisement atop a taxi cap, for the A&E television show Hoarders. The campaign utilizes clear panels on the rooftop ads, and fills them with old newspapers. You can get a good look at them below, in photos posted by blogger Ask A Copywriter.
Interestingly, he also spied the same advertisement removed from the roof of a cab, left alone and abandoned on a sidewalk of New York City. So many metaphors, yah?
