The profile appears to be quite well done but looking at the subject's style of clothing, I would guess it dates more to the mid 1900s than the 1800s. JMO.
An early albumen pic of Larkin Goldsmith Mead Jr., the prominent Vermont sculptor. Judging by the way the hair is always parted on the left side, I do not think the profile is a self-portrait. Probability, are there any markings on the back of the profile?
