(side note: I accidently said bordel, in reference to the mess of toys we had made, in front of the little girl I babysit and found out from her dad that I shouldn't use that word in front of children. oops.)
So Toulouse-Lautrec was also a raging alcoholic, and to hide his juice he had a special shot glass in his cane. Genius! The cane in the picture isn't the real one that I saw in the museum, but is from a shop in London called James Smith and Sons.
EDIT: this will be perfect for my mother, who just sustained a dancing-related injury.
