A penciled inscription, in the artist's hand, on the back of this famous painting reads: "The instruction of the new ones by Valentine the Boneless." A nickname given a nimble dancer who instructed the Moulin Rouge rookies in the can-can. Many of the inhabitants of the scene are well-known members of Lautrec's demimonde of prostitutes and artists. At the far right the Irish poet William Butler Yeats leans on the bar. The owner of the Moulin Rouge liked the painting so much he hung it over the bar.

Lautrec was born with serious congenital health condition which could be attributed to aristocratic inbreeding. Even his parents, the Comte and Comtesse, were first cousins. At the age of thirteen, Henri fractured both his femurs. Neither of the breaks healed properly, because of a brittle bone genetic disorder called pycnodysostosis (try and pronounce that!) which is frequently called Toulouse-Lautrec syndrome today. The injuries permanently halted the growth of his legs causing him to develop a full adult torso, while his legs remained child sized.

Lautrec popularized the cocktail. He was known for getting drunk off “earthquake cocktails”, which were a strong mixture of absinthe and cognac. He even hollowed out his cane, so that he could fill it with liquor. One of his drinking buddies was van Gogh, who he painted sipping a glass of absinthe. One evening they were so drunk that Lautrec offered to duel on Van Gogh's behalf, following a dispute with an equally drunken Belgian who had disrespected his Netherlandish friend. The vagaries of this lifestyle caught up with him, and he succumbed to the effects of alcoholism at the age of 36. https://bit.ly/3rgIT1c
