It is an observation, not an argument. I honestly had no reason to think about it until I saw a commemorative article about her yesterday, so I looked for some more pictures.

I worked out a lot to gain strength to pull my own weight. I was trim and muscled; my back was muscled. But I did not get a muscled prominent upper trapezius, even though I did trap exercises. The slanted muscle on the top of the shoulders. Other than serious body builders (and trannys) I have not observed traps like that on a woman. Just saying.
