Photographic Postcards

The University of Delaware Library Postcard Collection includes over one hundred fifty photographic, or "Real Photo," postcards—photographs of local businesses, railroad stations, schools, private homes, and landscapes—that document life in Delaware during the early twentieth century. They are ephemera of a distinctly local flavor—visual records of social gatherings, small town celebrations, fairs and markets, and local disasters.

Photographic postcards were created in small quantities, often by the amateur photographer, for the consumption of his own small circle of family and friends, rather than being mass-produced by a publisher and sold in retail stores. While many postcards are “stock” images of well-known sights and places, photographic postcards are more likely to be unique images. They capture a moment, preserve a unique view, or reveal the distinctive local character of a place.

Photographic Versus Printing Process


Photographic, or "real photo," postcards are true photographs that are printed on postcard stock using a photographic printing process. In a photographic printing process, a light-sensitive substance on a negative or printing paper turns dark when exposed to light to create the image. Most postcards with images that look like photographs are actually printed using ink in a photomechanical printing process, the same way that photographs are reproduced for publication in books.

Spontaneous and Unique Views

The production of photographic postcards was made popular and easy by George Eastman’s development of a light, hand-held camera—the Kodak. This simplified photography and launched a new breed of photographer: the amateur. Eastman’s camera was preloaded with one hundred exposures of film, so the photographer’s only job was to take the picture. After shooting the film, the photographer returned the whole camera to Kodak for development, and had the choice of prints or real photo postcards. In 1902, Kodak began offering a card back that allowed postcards to be made directly from negatives, inspiring photographers to document local attractions and to sell them in drug stores and stationery shops.

It is the spontaneous nature of a photograph that makes real photo postcards so remarkable. Amateur photographers and professionals alike created photographic postcards, often capturing unique views. A photograph of a firemen’s parade in Wilmington presents the celebratory march down a city street. Its outstanding vantage point, from the perspective of a young boy who has shimmied up an electrical pole to watch the parade, captures the immediacy of the event. The postcard is a rare view of the parade, which in a mass-produced postcard might have been depicted from street level.

Moments in Time

Photographic cards also are more likely to depict specific events and actions, rather than buildings and landmarks. It is likely that some photographic postcards are the only existing image of a place or event. At Rehoboth, a photographer who happened to witness a boat accident captured the reaction of the beach-goers in a photographic postcard, and called it “Running-to-the-Rescue.”

Rather than showing the aftermath of the event, as do a number of cards in this collection that show the wrecked ship on the beach, this photographic card documents a short-lived and immediate moment in time. Such a card has great value as a historic document, since newspapers rarely reproduced photographs in the early part of the twentieth century. In many instances, photographic postcards provide the only visual record of a local event or disaster.


Advertising Cards

Advertising cards made by a photographic process are rare. A photographic card that advertises Blue Hen Milk shows a herd of cows with dairy farm buildings in the background and a phone number to call for deliveries.

Portraiture

Photographic postcards were also a popular medium for portraits. Individual or group portraits commemorated a special event or recorded the membership of a club, often as a keepsake for the members’ scrapbooks. Less likely to have been mailed than other cards, portrait cards may have been treasured by their owners as personal memorabilia. These cards are now invaluable documentation of an organization’s history, and can help to trace individuals or gain knowledge about the organization’s membership in general. Two cards show, respectively, the members of Eden Lodge of Wilmington and the twenty-member Henry & Young’s Band of Wilmington.

Clues to Identification and Dating

Occasionally a photographic postcard was reprinted from the negative at a later date. Two images of Ye Olde Mill in Marshallton are examples of this. In this case, the backs of the cards show that they were printed at different times. It was not until March 1907 that a U.S. postcard could have a message written on the back. Until this time, only the address could be written on the back. The earlier image has an “undivided back,” indicating that is was produced before March 1907. The backs of postcards dating from March 1907 and after are divided down the center, with space alloted for a message on the left and an address on the right. A card with an identical image has a “divided back” and a message, indicating that this is a later printing of the same photograph.

Often the identification of the subject of a real photo postcard was written on the negative. This results in the caption appearing in white on the postcard. Still, there remain many cards without any identifying captions. Their subjects may be identified by the researcher interested in comparing the photographic cards to other surviving visual sources, such as personal photograph collections, town archives, and other postcards. For example, the subject of a photographic postcard with no caption can be identified as Brandywine Park by comparing it to other known views of the park.

Other cards may have no inscription, but their subject or location can be determined by studying small details in the image--sometimes under magnification. The site represented on a postcard of a railroad station has no caption, but a sign on the station reveals the town’s name: Kiamensi.

Some photographers printed their images smaller than the size of the postcard, leaving white space on the front of the card. Before senders were permitted to write messages on card backs, this space on the front was often filled with a message from the sender, identifying the place, time, or significance of the event. In one such postcard, the image of a church occupies only one-third of the space; the remainder of the space was left blank for a handwritten message. In the message, the church’s “Lookout Committee” appeals to the addressee to return to church meetings, from which the addressee has apparently been absent frequently.

Professional photographers sometimes ordered their names preprinted on postcard stock. W. B. Nichols was a Delaware City-based photographer who made cards with the name of his business, “Nichols Studio” or “W. B. Nichols Studio” printed on the back of his cards. The University of Delaware Postcard Collection includes postcards made by W. B. Nichols of Delaware City, and of Delaware College and Delaware Women’s College, the precursors of the University of Delaware.

Ed Herbener, a photographer based in Newark, Delaware, had his name printed on the back of some of the postcards that he sold out of his Newark Post Card and Music Shop. He also printed “Herbener Photo” in a corner of the image on some of his negatives, or stamped his logo and slogan directly into some of his photographs, promoting his popular “Best Series.” According to the Newark Post of February 9, 1910, Ed Herbener was “one of the pioneers in the postcard business,” and made many images of Newark, most of them postcards. Herbener’s inventions must have been very popular, for some of them, such as his photograph of Old College on the University of Delaware campus, were later made into photoengraved cards. Herbener recorded the sites of his own town, such as the Cooch’s Bridge Monument and the Pennsylvania Railroad Station in Newark, but also produced photographic postcards of Clayton in Kent County and Greenwood in Sussex County.

The Photographic Processes
The University’s collection of real photo postcards include cyanotypes, albumen prints, and gelatin silver prints, the latter being by far the most numerous. Named for their blue tone, cyanotypes were the product of an early photographic process introduced by John Herschel in 1842. While both albumen and gelatin silver prints depend on the light sensitivity of silver, cyanotypes are made by light sensitive iron salts and have no emulsion. To make a cyanotype, a piece of paper is sensitized with two different iron salt solutions and dried; then, the paper is contact printed (placed in direct contact with the negative) and exposed to sunlight until an image appears on the paper; finally, the print is washed in water, oxidizing the iron salts and developing the rich blue color.

The albumen print process was invented in 1850 and was the dominant photographic print process for the next fifty years or so. Albumen prints are named for their emulsion, which contains egg white and salt. After the paper is coated with this emulsion, it is placed in a silver nitrate bath to achieve light sensitivity. The paper is dried in the dark, then placed under a glass negative and exposed in sunlight until the image reaches a proper darkness. A bath of sodium thiosulfate prevents the print from continuing to develop and becoming too dark. Finally, a gold toning guards against fading. Albumen prints are capable of capturing fine detail, and have an even, somewhat glossy surface. Albumen prints are yellowish with creamy highlights and rich brown shadows, and have a tendency to fade.

By 1895, gelatin silver prints had replaced albumen prints as the most popular photographic process. Invented in 1873, gelatin silver prints use gelatin (an animal protein) as the emulsion, binding the light-sensitive silver salts to photographic paper. The gelatin print is a “developing out” process—the latent image that is made during exposure to light only becomes visible by development in a chemical solution. In a “printing out” process, such as albumen prints, the image appears on the paper when it is exposed to light. Characteristics of gelatin silver prints include silver mirroring in dark areas and true black and white tones.
