I don't know where I got this. I was going through my (very extensive) folders full of historical costume images, and found this. I've got no memory of saving it. The file name is "manet", so maybe we can attribute it to Édouard Manet, but I don't know for sure. That is French, I think, though it's rather impossible to read.
I'm now officially on winter break, so it's time to do some reading!
