RED CROSS mobile billboard

Nothing grabs an audience's attention more effectively than a clever optical illusion. Combine that with an ingenious ad campaign and you get this brilliant mobile billboard for The Red Cross, currently gracing the streets of San Francisco.
It's photo journalism, meets Hollywood blockbuster movie poster, and it is turning plenty of heads wherever it parks itself. Enthusiastic onlookers have been snapping up photos of the mobile billboard and posting, uploading and sharing them online with friends. This is a brilliant example of how an audience can further promote the exposure of a great advertising campaign through mobile phones, blogs and sites such as flicker. LINK
