Who is this French woman on a Japanese net page?

Thanks, Same Guest. I really appreciate it. You too eito(jpn). Once I knew who was being portrayed, I'd expected to find the painter without much trouble, but so far I'd had no success. I did find other pictures by Nattier, though, and in about the same style. I believe we now have the whole story -- Marie Adélaïde by Jean-Marc Nattier.

Bump.
