People and societies are the different actors in cartophilia. These are the printers, publishers, photographers, authors or publishers of books as well as the personalities represented on the postcards
The publisher is the person who gives the order to print the map. He takes the financial risk of editing the card and generally has the rights to the card.
Often the publisher and the printer are the same people in large series
In small localities the publisher is often the hotel or the local cafe, or even the hairdresser.
