The artist, however, has not. It is Jules- Alexander Grun, one of the most prolific poster artists of the era, with 135 to his credit. The use of a lot of black and red is one of his trademarks. Also very good at facial hair! The stippling is very typical of lithographs of the time, giving an easy sense of tonal variety.
We really need to look at the back to complete the story of this one. You will see it was posted in 1901, but the Trianon theatre had burnt down in 1900 and therefore it is presumably an old card sent by Monsieur Roux to a prospective client. Although his scrawl is largely indecipherable, the occasional reference to wine suggests that he is giving Monsieur Fleury a rundown of his rates for catering to a certain number of people. Passage de l'Opera was a posh arcade which presumably would be able to provide posh nosh etc. The other interest of the back is that it is undivided, meaning that before 1904 the message had to be written on the front. Hence the disappointingly small picture! After that date, they started putting a line down the middle of the back, creating the format familiar to us today. Clever, eh?
