Change

Possibly one of the most powerful arguments ever to be made with three colors, is the "Change" poster made to encourage voters for Obama. We see a kingly profile of Barack Obama, nothing more. And yet so much communication has poured out of this simple advertisement, one that made a profound impact on the American culture.
The first message is quite obvious, Obama can bring change. We do not see Obama and Biden, or anyone else, only him, almost as if he is the messiah who will bring change entirely by himself. Furthermore the poster tells us that he has started a new generation of candidates; no other candidate's face has ever been seen on a highschoolers t-shirt, let alone a celebrities. The Andy Warhol-like poster is sheik and modern, and over all young, as is the crowd it reaches. His eyes stare off into the distance, as if he has great plans ready.
More than any other argument, the poster is telling us that change is positive. After all, no one can make it to be the democratic candidate with negative catch phrase like, "Economic Destruction". Change is good. The kind of change apparently doesn't matter, because it doesn't state so, as far as the audience can see, whatever Obama does, will be good, because whatever he will do will be change, which is supposedly good. While on the other hand, his opponent must be offering no change, otherwise, it would not be a very creative, or effective poster.
The change poster sends a powerful message, one that may have won an election.
