Headley, and the picture of Sarah

[L Verge]

I think that John is onto something about this being a Kodak moment for Sarah. My only reservation is her bodice. I distinctly see a drop-shoulder sleeve line there that would have been passe by the 1870s. By the 1890s, we would start expecting to see the leg-of-mutton sleeves, which are very distinctive. The hairstyle is also more CW period than the Gibson Girl upsweeps of the 90s.
