How to Date Cards

By Jeremy Rowe

When people think about Ephemera, they typically think of paper – paper to which information has been added. Manuscripts are paper to which pencil or ink has been added. Trade cards, newspapers, bill and letterheads, menus and broadsides are paper to which ink has been added. Many, but not all photographs are paper to which a light-sensitive emulsion has been added.

Photographs are clearly recognized as Ephemera. Though in numbers, most photographs consist of paper and emulsion, popular photography began with images on silver-coated copper plates – the Daguerreotype – that was publically announced in 1839. Other non-paper processes were popular during the 19th and early 20th centuries. The ambrotype – a collodion photographic emulsion on glass – gained popularity in the mid-1850s, as did a less costly variant on japanned metal – the ferrotype or tintype.

Although alternative paper-based photographic processes, including salted paper and calotypes, paralleled the Daguerreotype, paper photographs didn’t begin to rival the popularity of other processes in popularity into the mid-1850s with the introduction of the collodion wet plate negative and albumen printing processes. Initial popularity of the 2 ½” X 4” (6.35 X 10.16cm) cartes-de-visite (CDV), or visiting card photo, and later the 4” X6 ½” (10.16 X 16.5 cm) cabinet card, along with larger format images became the formats of choice for photographers, who produced millions of paper images as the popularity of the daguerreotype and ambrotype waned. However, the tintype continued its popularity into the 20th century, largely due to its low cost and convenience.

Researchers interested in unraveling the information about a given photograph can take advantage of a number of embedded clues.

Specific photographic formats were popular during relatively limited periods of time and elements that changed can help date an image. The style of mat and case of the Daguerreotype, ambrotype and early tintypes offer clues. Occasionally written material or handwritten notes can be found in the case behind the image.

Card mounted photographs from the 19th and early 20th century, such as cartes-de-visites, cabinet cards and stereographs can be generally dated by their format and mount type. Printed mount notations such as photographer’s identification and title are fairly reliable, but can still provide false information.

Dating by mount type and style provides a rough indicator for identifying images. The caveat is that many photographers, particularly in more remote areas, failed to keep up to photographic fashion and used old mounts until their stocks were exhausted. Also, photographers reprinted historically or commercially important images long after they were originally taken. Also, negatives were often sold or copied and the mount information may not accurately reflect the history of the images. For example, D. P. Flanders’s views of Prescott, Arizona Territory taken in the Spring of 1874 appear on Williscraft mounts in the late 1870s, and Continent mounts into the mid-1880s.

Notations on the mounts can occasionally provide additional information about the image, but should always be verified by other sources before being relied upon. Handwritten notations are the most suspect, often being added long after the image was made by persons with only secondary knowledge.
