Thanks for the link .Am amazed at the image and that I hadn't seen the obvious detail that you saw right away. Really perceptive of you.
I agree about us all seeing things so differently,The other night I watched a TV show"Brain Games"and had the fact that we interpret things we see according to past experiences and training.Some times our brain jumps to conclusions which aren't factual but we are sure we observed one thing when another thing actually happened.
The first time I saw this image it was probably about 8 1/2" X 11" in a Avedon book and there were several of us looking at it together.probably one of us said" her hair seems to be moving" and that was enough to imprint on my brain (about 50 or more years ago).Sadly it makes a statement about my memory,LOL!
Again thanks, I believe you've answered my query
