Comics are just full of advertisements. From cover-to-cover, fanboys can learn about exciting products such as Wolverine bedspreads and Spider-Man toothbrushes. The back covers also house ads. Many comics will feature the exact same advertising, so fanboys are bombarded with repeated images.
On the back of many of Ash’s comics are advertisements for Spartacus, but not the old movie. I guess there’s a television show about him now. However, with all the comics piled up around my living room there are lots of Spartacuses. It really makes the “I’m Spartacus” scene from the film a little easier to act out with multiple copies.
