There is some confusion on what Real Photo Postcards (RPPC) are, and how to differentiate from a printed postcard.Real Photo Postcards are photographs that are reproduced by actually developing them onto photographic paper the size and weight of Postcards, with a Postcard back.
The best way to tell the difference is to look at the Postcard with a magnifying glass.As with all photographs, if you examine the images under strong magnification the you’ll see no dot or other printed ink patterns.Popular in the early to mid 1900s, real photo postcards picture a wide variety of subjects and were used for a variety of purposes.I, on the other hand, am crazy enough to think this might be something I can use.Would this be a journey of discovery filled with adventure and self realization?An ivory surface was introduced in the late 1940s by which time the standard Kodak names of surfaces were used.
The BB, CC and EE versions were primarily for contact printing. It was invented by Leo Baekeland who went on to develop Bakelite.
If the photo is printed, you will see that it is made up of a lot of little dots, the same as a photo printed in a newspaper.

Most Real Photo Postcards, abbreviated RPPC, have information on their backs to help in identifying the manufacturer of the photographic paper that was used by the postcard publisher.
If you can identify the paper manufacturer, you can approximate the age of the old postcard.
When friends asked Baekeland how he entered the field of synthetic resins, he answered that he had chosen it deliberately, looking for a way to make money.
