I guess a product of chance--a happy double exposure accident--yielding two partial consecutive shots of this pretty young woman with grooming brush in hand affectionately nuzzling her horse.  Formally excellent I think, with a conceptual art sort of feel to it. Perhaps it is her coat and hair and all those windows and of course the doubling, but keeps making me think of Hitchcock, while also, with horse as subject, like a nod to Muybridge's stop motions.
