You know, this is the kind of thing that keeps me up nights. I don't know if any or all of these were originals, but they give you a good idea of the kind of prints that were most popular in the Edo era - sumo, actors and women. (In keeping with the attitudes of the era, the women were invariably famous prostitutes.) These were the shining lights of the Floating World, and therefore the most popular images among the common people. It wasn't until the late Edo era that the subject matter became more genteel - pictures of generic beautiful women (bijin-ga), small pictures of flowers and birds (kacho-e) and landscapes.
What you're seeing in this picture is a re-creation of a bookshop of the mid-Edo era. In addition to the picture prints you see, there was also a selection of woodblock-printed books, bound with string.
