"An encounter between a lower-class prostitute and most likely a manual labourer. ...the design differs in focus and scale from the rest of the book.  The view is close up, and thus the conveyance of enjoyment is much more palpable to the viewer." excerpt from P.202, Japanese Erotic Fantasies, Chris Uhlenbeck and Margarita Winkel.
