Poker Under Arms

Buso Poker (武装ポーカー Busou Pōkā ) is a Japanese shōnen manga one-shot written and illustrated by Hirohiko Araki. Having been a "Selected Work" runner up at the Tezuka Awards, the wild west one-shot, Buso Poker, was Araki's first published work and the start of his debut as a Mangaka.

The tankōbon of Araki's other manga, Gorgeous Irene also features Araki's original works, including Buso Poker.

Trivia

 * Having been Araki's first work, some of the characters in the one shot have similar appearances and were probable influences of those from JoJo's Bizarre Adventure
 * One of the main characters that goes by the name, Mike Harper, has a similar appearance to Robert Edward O. Speedwagon and may have been a reference for the character.
 * The narrator of the story, having once looked like a old bum, has a striking resemblance to Dario Brando.
