The Kabuki actor Sawamura Tanosuke playing the role of the courtesan Iroha from the Kana tea house.
The subject is probably taken from a sewamono (世話物 / kabuki drama about commoners and ordinary people) of the late 18th century written by Takeda Haruzō (竹田 治蔵), a dramatic love story known as kane ga naru kesa no uwasa (鐘鳴今朝噂) that I like to translate as "A morning rumor rings the bell".
Inside the brownish cartouche that spreads along the right border of the print there is a poem that says:

土用芽は薄き色葉のもみぢ哉

Doyōme ha usuki iroha no momiji kana

Are the midsummer sprouts autumn leaves of light colour?
