Dating divided postcards
With the advent of World War I, the supply of postcards for American consumption switched from Germany to England and the United States itself.Most United States postcards were printed during this period.
These were illustrations on government-printed postal cards and on privately printed souvenir cards. Congress on May 19, 1898 granted private printers permission to print and sell cards that bore the inscription Private Mailing Card. Still, no message was permitted on the address side. postal regulations on December 24, 1901 stipulated that the words Post Card should be printed at the top of the address side of privately printed cards.In 1901, private printers were finally allowed to use the word "Postcard." These undivided back postcards often featured real photographs.Kodak marketed the Folding Pocked Kodak camera in 1906 that allowed the public to snap black and white photos and have them printed directly onto a postcard.The message was required to be written on the front of the card, next to the image.Therefore, as seen below, the image did not encompass the entire front of the card.
