|Postcard collectors call postcards printed
from a plate or negative by a photographic process on photographic paper "real photo
postcards", often abbreviated as "RPPC" on eBay. Kodak began
marketing postcard size paper in 1902 and other manufacturers soon followed. The
earliest postcards had undivided backs as the Post Office required that all messages be
written on the front so as not to interfere with the address. After 1907, postcard stock
was printed with a line dividing the back in half for address and message.
To see postcards of women and cameras printed by other processes, please go to the ephemera section of this site. For advertising postcards printed by Kodak, see the Kodakgirls section.
