Ehon double-sheet illustration. These images were most likely published in a shunpon signed 'Inransai' (淫乱斎), Eisen's most used name for pornographic works. One scholar translates the name Iransai as 'Vulva-mad studio', while we would translate it a little more literally as 'The studio of lechery'.
