I found a copy of the first and last print in our old condo when we moved in. Google: passe-temps des dames and see what you can find about those 2 prints. It didn't fit with our decor, so we gave them away. They had sustained a bit of water damage. I found the palette depressing. The frames were downright ugly. I doubt very much they had any real value. Better gone, in my view. I never missed them.
A friend told me to have them appraised because you never know. There is no damage at all and these appear to be in original or timely frames. I want to sell them but we do live in a 1910 home but it's not really something I would put up.
