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. If the postcard has a stamp box, click on one of stamp box links below. If there is no stamp box, or a generic stamp box, go to Postcards Backs.
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. There are many Postcards that reproduce photos by various printing methods that are NOT "real photos"...the same methods used when reproducing photos in magazines and newspapers. The best way to tell the difference is to look at the Postcard with a magnifying glass. 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. A Real Photo Postcard is solid, no dots.
