With RPPCs, I know that those made by DOPS can be dated to between 1925 and 1942.
Does anyone know what "DOPS" stands for? Was it a company?
Thanks.

re: RPPCs

I believe it identifies the manufacturer of the paper the RPPC was printed on. In this case Kodak.

re: RPPCs

One of the reasons I ask is that "DOP" refers to "Developing Out Process." In this process, the image on a photographic paper is brought out by being developed in a chemical bath.
On the other hand, "POP" (Printing Out Process) used strong levels of ultraviolet sunlight to bring out a visible image, rather than chemical development.
I don't know if "DOPS" just referred to "Developing Out Process" or if DOPS was an acronym for some company.
