In the lyrics book for the album Bone Palace Ballet by Chiodos, you can see a strange drawing of two swans, black and white, with their necks linked. This is a reference to vocalist Craig Owens, who has a black and white swan tatoo on his neck, which in a magazine interview he said, "They represent my impurities for all to see." People who didn't know about the tattoo or the article wouldn't have known about the swan egg.
