Artist's name?? artwork over King Marchand's bed

It's the one of a woman in a long, white dress lounging on a black sofa. Does anyone have any idea who's the artist??? I recently re-watching the movie and guess I'd never noticed it there before.

I bought a print of that exact piece of artwork about 40 years ago. I'm sure it's a rather generic piece of work, but I always wondered who did it. I've tried doing some searches, but haven't found anything on it.

Anyone know?
