Kudos, Pamela! Toulouse Lautrec's 1891 picture "Docteur Péan en train d'opérer" is mentioned in " The Last Lincolns" as he was the first to operate on Jack's carbuncle. Kudos also to Laurie for identifying HTL!

Here's some info on the picture:

Pamela, you win tickets for the first cabaret, "Le Chat Noir", whose famous ad was a Lautrec artwork, too:
