I think the problem with the acutal photo is that it is taken from an actual photo. She was smiling therefore the smile lines around the mouth and eyes are more accentuated but, to be honest, Diana was an avid sun worshipper and I am afraid that there are more than a few 50 year old women around that wish they had not used more sunscreen.
20 years ago we were almost totally unaware of the dangers of sun damage and people were just literally frying themselves and that really ages the skin.
As for the neck and decollatage? Well, it is just a little more accentuated than Catherine's.
As to actually producing an aged photo of Diane? Creepy and, well I can't see the point. As to putting Catherine in the "frame" so to speak? That isn't just creepy, it's deeply disturbing and reflects the unhealthy (ok, just plain sick) attitude of the photographer and the writer.
Catherine has never met Diana and to speculate on any type of relationship at this level is the outworking of deeply distubed individuals who obviously worship Diana in a totally unhealthy way. So, not only does Catherine get to contend with an historical icon, the late Diana, Princess of Wales, she gets to see herself walking, talking and smiling to a spectral mother-in-law!
Is anyone else as deeply grossed out as I am?
