In 1906, Kodak introduced their Folding Pocket camera, the first camera aimed at a mass market. One feature of this camera was the ability of the photographer to write a message on the negative with a metal scribe. These negatives were postcard sized and could be printed onto paper with a postcard back. Black-and-white “real photo” postcards made in this way and also by professional manufacturers continued to be popular until a new process for producing colour postcards, called “photochome” or “chrome” was invented shortly before the Second World War and came to dominate the industry after the War ended in 1945.
Because Real Photo postcards are produced directly from actual photographic negatives, they give an unaltered glimpse of early 20th century life. As a result, they are generally more sought after by collectors than the more colourful lithographic postcards of the same period.
