The very first photographs made were on printing out paper.Light energy alone, usually from the sun, reacted with the light sensitive chemicals on the paper’s surface to produce an image.They only needed to be fixed to preserve the exposed image.The simplicity of the process made it very attractive to amateur photographers.Kodak controlled 80% of the paper market with their brands Artura, Azo, Aristo, EKC. Cyko by Ansco, Argo by Defender, and Kruxo by Kilborn comprised most of the remaining market.Many other brands of photo paper were also manufactured in Europe but rarely left the continent.

In printed images the grey areas are usually made up of black marks that are spaced to create the optical illusion of greys.

NOTE: There were many other photo papers manufactured in addition to those listed on this page, and even these could be made in different finishes from matte to glossy.

At least 450 different real photo postcard backs can be found but as of this time there is a lack of accurate information regarding all their dates of use, or they were used in very limited quantities.

When no postmark is available, the type of materials used can often aid in narrowing down the years it may have been produced in.

This too is not foolproof for many publishers had large stocks of photo papers using them for decades after they stopped being manufactured.
