Ambrotypes were introduced in the very early 1850s and photography left them behind around the 1880s when other easier methods came into being. Nevertheless there is something charming about an ambrotype which lifts it above the ordinary carte de visite of later years. The ambrotype has 'class'.
This lady - who also has class - dates to the first decade of the sixties, her hair worn with a central parting and her ears demurely covered.
No photographer's name is given.
