The magnificent Ambrotype at actual size, showing the pad with the desirable Vance imprint.

Vance imprint at 250%. Who was Robert H. Vance? Simply the best-known Gold Rush photographer and arguably the most desirable.

Vance was also responsible for one of the great lost treasures of America. Briefly, the story is this: In 1850 and 1851, during the height of the California Gold Rush, Vance traveled throughout Northern California, taking some 300 daguerreotypes of the cities and town, mining and miners, probably Indians and Indian villages and more. The dags he took were whole plates, meaning twice the size of the ambro shown here, and comparable to the 200% enlargement pictured below. This was the largest size available at the time. Each dag was mounted in a custom rosewood frame, and each had outstanding display value. Vance took them to New York for exhibition, but they were a financial loss. He sold the lot and they went through a couple of hands, eventually ending up with famed St. Louis photographer John H. Fitzgibbon. Fitz left the country during the Civil War and the dags were never seen again.
Now, other than their incredible historical value, what might be their monetary value today, were all 300 to be found in perfect condition? If we figure each dag as having a current value of, say, $100,000, the lot would be worth about $30,000,000 (thirty million dollars). That I believe would be a reasonable value. And it's very likely some would be worth $250,000 each.
But if they do turn up as one lot - and it's not all that farfetched that they will someday - I hope that someone will publish a high-quality book of photographs of the bunch that the average collector and historian could afford.

The back cover of this wonderful case.

Ambro at 200% (twice actual size). What's wrong with it? Well, ambrotypes inherently do a poor job of copying dark colors. Notice how the father's clothing blends into one shade and practically disappears, while the mother's dress shows considerable detail, as does the girl's top. A shame the dresses weren't colored.

The Ambro at 200%, but enhanced (contrast added).

The image at 300%, enhanced. From the clothing I would date this at about 1858.

The image at 500% and enhanced. It can well be imagined that this fine family photograph was one of the prized possessions of the girl throughout her life. Perhaps it was passed along to her descendants, but regretfully somewhere along the line it got sold off and the people's identities were lost. What a pity. Nevertheless, this was obviously a well-to-do family, probably in San Francisco or the vicinity, and it's very possible that someone who sees this photo on the Internet will know who they are and will contact me. I certainly hope so.
