An 1880s poster for Strange Case of Dr Jekyll and Mr Hyde, a novella by Robert Louis Stevenson known for its vivid portrayal of a split personality, wherein within the same person there is both an apparently good and an evil personality, quite distinct from each other. It was a huge success, with over 40,000 copies sold in the first six months after publication. (POTD)
