I doubt it. If Dark Horse isn't even willing to make the cover for 23 point the right way, I don't think that they would go out of their way to include a poster; that's expensive. If you read one of Chris Warner's earlier posts, he estimates that 97% of people who buy the DH releases of Berserk are 'casual readers', or people who wouldn't know or care about posters in the later volumes. But I hope that I'm wrong.
