Speaking about the auction, Hayden said: "Dolphins and whales are the barometer to the health of our oceans. As go the dolphins and whales, so go the oceans, and then so goes life on earth. "It's simple, if we save the whales, we can save the world."

Other auctions from the same seller include a dress that Hayden wore for her Candie's photoshoot, bracelets, shoes & earrings, jacket & poster, and a signed poster.
