You old gray ad-silverbacks (gasp, like me) with a longer advertising memory than five minutes will know that yes indeedy, the flags-in-dogpoop advertising media has been around for at least ten years. Kesselskramer did it back in the 90s, Miami did it a few years ago, and countless student portfolios have had dog-shit-flag ideas in them forever. We've been mocking the dog-poop-flags here since at least the year 2k (see last image).
But have you seen it applied to political advertising before? Thought not. Here are some flags likening McCain's promises to dog poop.
Granite Pass is a fan of Barack Obama and so, in true election advertising style, they threw some shit at McCain. Toothpick flags were used on sidewalk dog poop. See more at http://flickr.com/photos/31219120@N03/
I'm not sure it's helping Obama much.
