This is a B2 Japanese poster, printed in 1984, for the movie “Nausicaä of the Valley of the Wind” (風の谷のナウシカ).

Based on Miyazaki’s own manga, “Nausicaä of the Valley of the Wind” tells the story of Nausicaä, the princess of a small nation who lives in a world devastated by a holocaust called the “Seven Days of Fire”. She tries to stop other warring nations from destroying themselves and from destroying the only means by which their world can be saved from the spread of polluted wastelands.

While created before Studio Ghibli was founded, the movie is often considered to be the beginning of the studio because of the involvement of Studio Ghibli’s Hayao Miyazaki, Isao Takahata, Toshio Suzuki, Hideaki Anno and Joe Hisaishi. Because of this, Studio Ghibli generally includes Nausicaä as a “Ghibli film”.

The poster features Nausicaä and an Ohmu.

According to the information on ghibli-museum-shop.jp, the book “The Archives of Studio Ghibli, Volume I” and “Studio Ghibli: The Complete Works”, this is a special poster drawn by Hayao Miyazaki and it was used as a gift when buying advance tickets for the film’s release. Also, since the poster doesn’t have the Eirin Mark, which is pretty unusual for Studio Ghibli’s original movie posters, I would say that this information is quite reliable.

However, it is true that this poster resembles an advance movie poster, as it has very little information. These type of posters were issued before the movie’s release and used for appetite and whip up frenzy for the movie.
