This is a copy of an earlier photo–certainly either an ambrotype or daguerreotype. Photographers Broadbent and Taylor, or whoever owed this image, drew strengthening lines around the woman’s shoulders and head, as well as around her eyes and possibly lips. On the actual Cabinet card, these lines are not really noticeable, but when blown up, they become quite evident.
The sitter wears fashions that date the photograph to the 1850s. She wears a mourning brooch at her throat, its hair compartment and black enamel clearly visible. I have a similar brooch in my collection. The otherwise lovely piece below suffers from moisture damage. At some point in the past, water or humidity seeped into the brooch and now the hair is a shade of green, dyed by the metals that surround it. Ω
