Audrey Flack - photorealism

I know that most of the time I write one/two sentences about the artist I feature. But this time, I'll simply say it's one of the founding fathers (mothers?) of photorealism. What is the most incredible for me is that's done in oil. For those of you unfamiliar with painting, it is pretty much impossible to master.
