From the 1994 book Ship of Dreams page 12.

A voice boomed through the darkness at Joey who was entangled in the net, suspended high in the sky. A strange ship with its sails billowed out and a great balloon rising from its center was drifting ever closer. An old man bellowed from the deck, “Who's there?” It was the Sandman - and Joey's real adventure was about to begin. - Dean Morrissey
