I say “vintage”, because it looks “vintage-ish” and I found it in the vintage groups on UseNet:
But I am uncertain, truth be told. There’s something about the picture that sets off my “modern art photo with a deliberate retro look” warning. Maybe the shoes, maybe something in the filtering and lensing, maybe it’s just that it looks too much like something Ellen Von Unwerth would do.
So if you recognize the pic and have a photographer credit or a source, I’d love to have it. Of course that’s also (and always) true if it’s a vintage pic as well.
