Attractive anon- ymous photo of parents (presumably) and three daughters: certainly the four females here look very much alike. Impossible to tell, though, about the dad. As one's eyes move from right side of image to left--present to past, as it were--the figures fade out (via overexposure). By the time we reach the father he is a mere clownish blur, with only suspenders, legs, and freakish gigantic hands in focus.
If the photograph is an allegory, I'm not quite sure what it's an allegory of. The historic (and apparently irreversible) feminization of the modern human subject?
