The history of postcards.
The history of photography is less than 170 years old. In 1837 Louis Daguerre developed the Daguerreotype process, creating images on silver-plated copper, coated with silver iodide and "developed" with warmed mercury. Plates were wet, slow to develop, and generally, left to the professional. In 1871 Richard Leach Maddox, an English doctor, simplified the process by the use of an emulsion of gelatin and silver bromide on a glass plate, the "dry plate" process. By 1888 the first Kodak camera was available, and in 1900 the Kodak Brownie box roll-film was introduced.
The first privately made postcard, where postage had to be affixed, was introduced in Austria in 1869 and by 1870, picture postcards were all the rage!
Postcards such as the ones pictured here are collected and sold on the internet.
