Well, I kinda want one of those posters, so I just went ahead and emailed Vertical to ask if they'd send me one. No harm in asking, right?
I also dropped a line to my comic shop (Hub Comics,
http://www.hubcomics.com) and asked them to get some of the posters since I'll be buying the series through them and maybe getting the poster up and the books on shelves will get some other readers hooked.
I'm foaming at the mouth for this series, by the way. The Dezaki/Sugino OVAs were really my 'gateway drug' to Tezuka's body of work, and it's long been my favorite. I've owned the hardcover Akita Bunko (Japanese) and softcover Glenat (French) releases for years and am looking forward to augmenting my collection with a version that I can read without a dictionary and lots of guesswork.
Oh, well-- in the meantime, there's a new Dororo this week!
