Documentation about Information object: Postcard back template
The back of postcards is often a source of information on the producers of the cards: publishers, printers, illustrator, photographer but also on series. On the other hand some backs do not contain any information BUT the back, even without indication, still allows you to draw information on the card
The most important info is to see if the back is split in half by one or two vertical lines. An undivided spine indicates that the map is (usually) prior to 1906 (this date varies from country to country)
Other details make it possible to gather as a family and identify the printer.
The aim of this module is to be able to identify printers a priori anonymous by precisely coding the invoice on the back of the card.
The goal is not to pick up all the card backs with logos and series, the goal is to help identify the card when there is no other usable information.
Priority is given to undivided backs .
The scanning of the back of the cards can always be done in the card of the postcard itself. Preferably we will put a scan with a date, i.e. the stamp is readable or that the signatory has himself dated the document
