Lightle, Steve - DC Superhero pencil sketches

Description	:	These are some nice preliminary pencil sketches by Steve Lightle. These were done for a project for the public school system (I don't know what city), in co-operation with DC Comics. I get a big kick of out of the panel where Aquaman's picking up garbage, but I think it would have been funnier if Steve had drawn had him spearing the garbage with his hook. $150 What is this?
