The Victorian tradition of pornography in the UK consisted of three elements: French photographs, erotic prints (sold in shops in Holywell Street, a long vanished London thoroughfare, now Aldwych,) and printed literature. The possibility of mass production of photographs helped the rise of a new business types, the porn dealer. Many of these dealers took advantage of the post office to deliver photographic cards in plain envelopes to their customers. Thus a reliable international postal system facilitated the beginning of the pornographic trade. The Victorian pornography had several defining characteristics. It reflected a very mechanical way of looking at human anatomy and its functions. The science was used as a new passion, ostensibly to study the human body. Here, the viewer often depersonalized sexuality of the subject, which had no passion or tenderness. At that time it was also becoming increasingly popular to depict nude photographs of women of exotic ethnicities, under the guise of science. Such studies can be found in the work of Eadweard Muybridge. Although both men and women he photographed the women were often equipped with props such as market baskets, or rods, which made these pictures too thinly disguised erotica.
