A muzzled, teary-eyed, and jaw-bound Jessica Alba appears in a provocative and compelling new ad campaign encouraging young adults to get active in the upcoming presidential election.

The striking ad is for "Declare Yourself," a non-partisan, non-profit national voting initiative aimed to get young voters to register and vote in the 2008 presidential race. The ad bears the slogan: "Only You Can Silence Yourself."

"These images, while incredibly unsettling, are extremely compelling to today's young adults," said Marc Morgenstern, Declare Yourself Executive Director. "With less than 40 days left until the national election, we deliberately chose vivid and startling imagery to break through and underscore the grave consequences of not voting and in effect muzzling oneself."

The dramatic, eye-popping photo of a struggling Alba was taken by renowned photographer Mark Liddell.
