VIPER Original Illustrations Collection- Official art retailer book (4)

Product Name: VIPER Original Illustrations Collection- Official art retailer book (4)
Super rare here in the United States. I'm not too familiar with this series but it seems to be some sort of hentai. The book does contain graphic visuals and is definitely not for children or people under 18. This is in like new condition only has a small ding on the corner and a small one on the dust jacket. Comes with the poster still inside as well as the three pack cards and other inserts as shown. Will ship via ups and will retailer be bubble wrapped and placed between cardboard.
