The artistry of retouching aside - I think there were several poses and photos made during this sitting.
There are many subtle differences between this (Baxter's) photo and the one in QD page 194.
Agreed, though, the retouchers were masters of their art and we can probably never discern what changes they made. It's a good lesson.
