In the May issue of Asuka magazine there is a large Saiunkoku Monogatari poster! It’s really nice :)!
Additional stuff in the magazine:
- Psychic Detective Yakumo Book Cover
- Zone-00 Postcards (the package is nice, so I’m afraid to open it)
- Anime series preview DVD
- Oh, and the Kyou Kara Maou color title splash page is ADORABLE!!!!
I bought my copy from Amazon Japan.
