A rare original 1980 unfolded U.S one sheet theatrical poster for Shogun Assassin,  a  cult film about a medieval Samurai, Lone Wolf (Tomisaburô Wakayama) who pushes a baby cart holding his son (Masahiro Tomikawa), who narrates the story. 
When the wife of the Shogun's decapitator is murdered and he is ordered to commit suicide by the paranoid Shogun, he and his four-year-old son escape and become assassins for hire, embarking on a journey of blood and violent death.
 
Many of the lines from this movie are sampled by hip-hop artist and Wu-Tang Clan member the GZA on his album "Liquid Swords". And Tarantino references the film in Kill Bill. 
 
Shogun Assassin was edited and compiled from the first two films in the Lone Wolf and Cub series, using 12 minutes of the first film, Lone Wolf and Cub: Sword of Vengeance and most of Lone Wolf and Cub: Baby Cart at the River Styx. Both were originally released in 1972. These were based on the long-running 1970s manga series Lone Wolf and Cub created by the writer Kazuo Koike and the artist Goseki Kojima.
