Every. Single. Japanese. Godzilla. Poster.
Ever.
Especially
Noriyoshi Ohrai's illustrated, Heisei Era posters.
[Pictures were too big for this post.]
Godzilla Vs. Biollante [ゴジラvsビオランテ] (1989)
Godzilla Vs. Mechagodzilla II [ゴジラvsメカゴジラ] (1993)
Godzilla Vs. Destoroyah [ゴジラvsデストロイ] (1995)
These were only couple of Heisei Era masterpieces. There is also some colorful poster on the Showa.
Actual horror posters that I would like to have, hanging on my wall.
Some 50's science fiction/horror posters are pretty neat too!
City of The Living Dead [Paura nella cittą dei morti viventi] (1980)
Just, haunting... This was too big too
Japanese Evil Dead-poster. These were colorful.
//But wait! There is even more! (Going to post later some more favorites.)
