Ahh, it's an oldie!
At first, I was wondering how they'd be able to legally sell off a nuclear-powered aircraft carrier to an ebay buyer, but then I read the fine print. I'm sure some local navy guys would be able to clarify, but that's a WWII baby carrier. It's much smaller than you'd expect. An Iowa-Class battleship from the same era would absolutely dwarf this.
Fairly expensive, really.
