From Flickr user Sangsara, who shot the image of a cow atop a bus for a flavored milk company, comes this interesting in-bus ad concept. Along the hand rail, small promotional packages for drug company Pfizer are hung. The ads seek clinical research volunteers. While Pfizer surely hopes people grab these hanging ad handles, we sure hope commuters grab the real handles when the bus comes to a stop lest there be a pile of injured, ad-carrying people at the front of the bus. View close up shots here and here.
