The two cartes-de-visite on this page came from an antiques dealer in Greenfield, Massachusetts, in the northwest part of the state. On the back of the carte above is the name Adolphe with a question mark:
The portrait was made at the studio of E.v. Eggert, which probably stood for Emmanuel von Eggert (see visitor comments below). One Latvian website uses the name Emanuels Egerts.
The carte below was made at the same studio, at the same address, but it has a different design on the back. The sitter is an older man and the card itself looks considerably older. On the back is the name “Abraham Z.”
Abraham may have been Adolphe’s father or uncle. The names are written in different hands, and the question mark after Adolphe’s name suggests he was a distant relative of the writer, rather than a direct ancestor.
