吉原遊廓の遊女の最高位は何？
The prints depict and contrast women who work in or near the exclusive pleasure district of Yoshiwara in the administrative capital of Edo (modern Tokyo). They range from the highest ranks—highly-trained and expensive geisha and "oiran"—to the lowest prostitutes outside the walls of Yoshiwara. Each is printed on a yellowish background and bears a different-coloured inkstick-shaped cartouche in the corner displaying the series name. The title alludes to and puns on the name of a "haikai" poetry anthology that appeared in 1731.
