This is the language in which the title of the postcard is written

If the card is multilinque choose the appropriate option (for example French / Dutch)

If the card does not contain a title (as often the fancy ones) one will use the language in which the card was described

The postcard in a broad sense is the heart of this site. It includes all sizes of card stock intended to be sent in the open including photo-cards identified or not

The photo card has the "photo-card" printing mode. If the photo map is identified we can specify the locality, otherwise there are generic localities for each country or province of Belgium.

Different postcards will be created if the snapshots are different for the same map of a series or if the reference number is the editor or if the title is completely different. The variety of colors or presentations or title place will only be specified if this presents crucial information for relatively rare cards.

If there is a coherent set of cards from the same publisher or printer, the card will be associated with a series and possibly a set of postcards. A card set is a subset of a series of cards. See the associated documentation.
