I was going through some posters today which were in storage and I completely forgot about these three posters. I remember buying them around 7 years from Yahoo Auctions Japan.
The auction was for the two Vampire Battle 94' posters and the Vampire Hunter Vol. 2 Anime Promotional one came as a bonus from the same seller.
I've not seen the Vampire Battle 94' posters come up for sale since.
They were for the official Capcom tournaments around Japan in 94 which would of be held in different arcades across Japan. I guess these just went unused!
