Advertising companies seem to have access to an expansive database of Victorian pornography that I don’t know about. My favorite book on the subject is 1000 Nudes, and I feel that it has a monopoly on the subject. But every so often I’ll come across a Tekserve or random alcohol ad that taunts me with its lack of citations. This isn’t strictly Victorian (1920s, maybe?) but I place it in the same category because of its aesthetic.
