I did think for a long time that it must be Sylvia Sims.
I have done a face comparison on old photos of Sussanna York and I
do think it is Susanna. The reason I think so is her eyebrows.
Even on old photos in different films Susanna always seems to have
the right eyebrow shorter than the left one. If you measure it down
over her eye the left eyebrow matches up with the corner of her eye.
The right one is always slighty shorter and never matches the right
corner of the eye.
I notice as well her neck she has a really noticable vein in her neck on
both of these photos you have now shown side by side.
I have seen a photo of her in Yellowbeard and she has the shorter
eyebrow and the vein in her neck. I have looked at my neck and I
havent got a vein like that in mine. I do hope this is Susanna as I want
to know
