I'm trying to find the author and the title of a painting that I vaguely remember.

The painting shows a man painting a woman. It looks like an ordinary self portrait but if you look closer you will see that the painted woman has an arm going out of the picture and is directing the arm of the painter.

I think the painted woman was the master of the male painter?

I think it's from Italy, 17th century (very vague reminiscence here)?

I keep thinking about Artemisia Gentileschi but can't find any link to something similar

Any help would be appreciated, it's driving me crazy
