This is a Japanese B2 Poster (20.3" x 28.7") for the 1972 Japanese animation feature, HellHound Liner 0011 Transform!  and as "Maken Liner-0011 Henshin Seyo!" in Japan.

In a far distant future, professor Hayashi is trying to alert the world to an alien invasion, but is being ridiculed instead. Saved by four dogs his son Tsutomu befriended, the professor transforms the four dogs into cyborgs with incredible abilities. Led by Tsutomu; Queen, Ace, Jack, and Joker will together fight the alien menace.

HELLHOUND LINER 0011 TRANSFORM!, or as Toei would like you to know it, “Go Get Them 0011”, has a solid anime pedigree with direction by Takeshi (Captain Harlock, Great Mazinger, Grendizer) Tamiya and a script by Tsuji Masaki and Toei legend Yugo "Little Prince And The 8-Headed Dragon" Serikawa. However, it's Hiroshi Sasagawa whose imagination powers HELLHOUND LINER - the film is based on his 1963 Shonen King serial "Hellhound Goro", and Sasagawa would go on to a long and fruitful career at Tatsunoko, where he'd give TIME BOKAN its sexy Doronjo-sama and let CASSHAN's transforming robot-dog-jetplane Frenda out of the robot-dog-jetplane kennel.
