NCIS star Pauley Perrette's autographed NOH8 Campaign photos are being auctioned off to benefit the group.

Perrette, who is best known for playing forensic specialist Abby Sciuto on the CBS detective drama NCIS: Naval Criminal Investigative Service, has autographed two 12”x12” glossy prints to be auctioned off by the group on Ebay. (Video of Perrette autographing the photos is embedded in the right panel of this page.)

The NOH8 Campaign, which is helmed by photographer-activist Adam Bouska and his partner Jeff Parshley, raises awareness and funds for gay rights causes, including ending California's 2008 voter-approved gay marriage ban, Proposition 8.

In one photo, Perrette poses with her mouth duct taped while wearing the strapless white dress with the NOH8 Campaign logo that she debuted in January at the People's Choice Awards.

The 42-year-old actress told reporters at the awards show that she envisioned the dress and asked her favorite designer, Terri King, to create it.

“I had an idea for this dress and I went to my friend Terri King – brilliant designer – and I was telling her about it and she's like 'Let's do it,'” Perrette said. “And she made it. It's flawless. It's exactly what I wanted.”
