This first thing I must say is that I have no idea who it is. However I do remember seeing it before: several years ago when I was trying to sort out some old family photographs. At the time I asked my mother and father who it was a photograph of, and they had no idea. The recognised family photographs were filed away - the mysterious couple must have remained in the box... forgotten.
So who on earth are this odd couple? Is it a man and a women or two women? If the latter, why the bizarre clothing? And what was the occasion? If you look closely you can see it is not a studio photograph, there is grass underfoot. Could it have been taken at a fair or a showground?
It makes you want to write the back-story. Look at the faces closely. Could they be sisters? Arnold Bennett once so two such elderly sisters sitting at a hotel dinner table. His imagination was set in motion and he wrote "Old Wives Tale" (one of his best novels). There is a confidence about the two figures... no shrinking violets these .... no caged rabbits.
