“Space Amoeba” (ゲゾラ・ガニメ・カメーバ 決戦! 南海の大怪獣), Original First-Release Japanese Movie Poster 1970 — Dead Stock, Very Rare, B2 Size (51 × 73 cm) B120

This is an original Japanese B2 theatrical poster printed in 1970 for the first release of Space Amoeba (ゲゾラ・ガニメ・カメーバ 決戦! 南海の大怪獣), produced and distributed by Toho. A late-Showa creature-feature cult favourite, it’s a glorious blend of sci-fi paranoia and tropical “monster-island” chaos—exactly the kind of Toho oddity that has only grown more collectible as the years pass.

Film background
Directed by Ishirō Honda and produced by Tomoyuki Tanaka (with Fumio Tanaka), Space Amoeba tells a brilliantly pulpy story: amoeba-like extraterrestrials hijack a space probe, crash land on a remote Pacific atoll, and begin transforming native life into towering kaiju. The result is a trio of unforgettable monsters—Gezora (giant cuttlefish), Ganimes (stone crab), and Kamoebas (mata mata turtle)—brought to life with Toho’s trademark suitmation ingenuity and special effects by Sadamasa Arikawa.
The film later received a U.S. theatrical release via American International Pictures under the title “Yog: Monster from Space,” cementing its reputation as one of Toho’s most entertainingly strange imports.

Poster design
This B2 is peak Toho theatrical energy: an explosive South Seas battlefield rendered in rich sunset tones. Gezora dominates the left with surreal, wide-eyed menace, while the airborne Kamoebas and the clawing Ganimes drive the action across the centre. The lower section is packed with classic Japanese “spectacle montage” elements—tiny fleeing figures, cast portraits, smoke, fire, and scale—while the enormous red title 「決戦! 南海の大怪獣」 (“Decisive Battle! Giant Monsters of the South Seas”) lands like a giant stamp across the bottom.
For collectors, it’s one of those designs that feels instantly of its era: bold colour, maximal drama, and that unmistakable Toho monster-pageantry.

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.

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