Put your head in the ground

Yesterday I saw these huge banners hanging in the 30th street train station in Philadelphia. When I got there in the morning I only saw the first one, and I was pleasantly puzzled .... I couldn't wait until this mysterious ostrich thingy revealed itself as the advertisement I knew it would become. Later that day I strolled back into the train station, and low and behold, on the opposite wall there was the second banner.

The headline reads: Get a world view. Read the Economist.

Not sure what agency did this ad ... maybe Ogilvy? But as far as I'm concerned ... you can't go wrong with giant ostrich posters.

* Update: Agency is BBDO N.Y.
