Rodolphe Salis opened his cabaret in 1881, Salis gave the name, apparently after taking in a lost Black Kitten. It became famous for the décor done by various artist of the day and the poets/song writers that assembled there. Salis installed a piano, which was a huge novelty at the time and helped the Chat Noir become one of the most fashionable places of Paris.
Steinlen, who was a Catophile, was in his element portraying a cat in this poster for the cabaret.
