Poker Under Arms is a Japanese shōnen manga one-shot written and illustrated by Hirohiko Araki. Having been a "Selected Work" runner-up at the Tezuka Awards, this Wild West one-shot was Araki's first published work and marks his official debut as a manga artist. The one-shot is included in Gorgeous Irene, a volumization of Araki's other early manga.
The story follows two wanted outlaws, Don Peckinpah and Mike Harper, who find themselves facing each other in a game of poker. Both players are willing to go to any lengths to win, even if it means gambling with their very lives.
