“Zero Monster” / “Invasion of Astro-Monster” (怪獣大戦争 キングギドラ対ゴジラ), Original Japanese Movie Poster 1970, Toho Re-Release — Dead Stock, Very Rare, B2 Size (51 × 73 cm) P53

This is an original Japanese B2 theatrical poster printed in 1970 for the Toho re-release of Invasion of Astro-Monster (怪獣大戦争, 1965), issued in Japan with the punchy campaign billing キングギドラ対ゴジラ (“King Ghidorah vs. Godzilla”) and often referred to in international markets as “Zero Monster.” It’s one of the key mid-60s entries where Toho kaiju collides head-on with pure sci-fi—aliens, space travel, mind-control, and monster warfare—making it a cornerstone title for collectors of the classic Honda/Tsuburaya era.

Film background
Directed by Ishirō Honda with special effects by Eiji Tsuburaya, Invasion of Astro-Monster is a defining example of Toho’s 1960s spectacle engine running at full power. Aliens from Planet X (the Xiliens) request Earth’s help to stop King Ghidorah—only to reveal their real agenda: gaining control of Godzilla and Rodan and unleashing them as weapons. The result is an all-out monster war that blends space-age paranoia with Showa kaiju scale, and it remains one of the most influential “alien invasion” entries in the franchise.

Poster design
A sensational, high-saturation re-release design: King Ghidorah dominates the right side in blazing gold, his three heads firing gravity beams into an apocalyptic sky, while Godzilla battles from the left in a storm of light and colour. The UFOs and cosmic setting foreground the film’s sci-fi identity, and the lower montage locks in that classic Japanese theatre promise—astronauts, Moon-surface imagery, and “monster war” stakes compressed into one dynamic sheet.
Typography is bold and period-perfect: the massive title block pairs 「キングギドラ」 and 「ゴジラ」 in thick yellow with a central “対” (versus) stamp, while 「怪獣大戦争」 (“Monster War”) sits above as the franchise-scale headline. It’s instantly readable from across a room—pure Showa-era wall impact.

Rarity and condition
This particular example is exceptional: unused cinema dead-stock, sourced directly from the remaining inventory of a theatre that has since closed. Because it was never displayed, the presentation is clean, crisp, and refined, with striking “gallery wall” impact—especially in a design that balances saturated colour with large areas of pale space. Dead-stock Toho re-release B2s from this era are increasingly difficult to find, and this one presents as a true collector-grade survivor.

Condition
Excellent, close to Near Mint (Unused “Dead Stock”). Please review the photos—they show the exact poster for sale.
