If you look closely at the other side of the star spangled shark, you can see Arnold Schwarseneger's signature.

Cameron L. Spitzer never saw this shark. However, we were talking about how much we enjoyed Arnie's Science Fiction films, and I mentioned seeing this. He said that another shark that I hadn't seen had been decorated with old circuit boards, many of which he had signed the schematics for. I got that "there is more than one kind of hero in this world" feeling.
