1970-Present The Continental card is made by the same process as Chrome cards, but is a slightly larger format, usually about 4 x 6 inches. This seems odd since similar shaped edges were popular on Carte-de-Visite and Cabinet cards from the 1880s.Although larger cards dominate this period, (including many odd sizes larger than the Continental, or smaller than standard cards) standard size cards continued to be produced in smaller numbers. Perhaps these were formally discouraged by postal regulations, though I haven't seen any such references yet.These can be easily distinguished by examination with a magnifying glass, as lithographs are screened (made up of small dots). There are however, printing processes that produce photographic reproductions without the dot-pattern of a screen, such as the Albertype.1901-1907 The Undivided Back period, is a slight mis-nomer, since Pioneer and Private Mailing Cards (as well as early real-photos) all had undivided backs as well, but this period marks the beginning of cards labeled Postcard or Post Card and having an undivided back.
More likely, the white border was made to resemble similar borders found on photographs (caused by the unexposed edge of the negative, which was contact-printed).Since most white border cards were taken from photographs (art cards of the same period rarely have white borders), the border makes them appear more like the photographs people were familiar with. Most writers describe these as cards printed on higher quality paper, resembling linen.I think they are simply the same old cardstock embossed on front with fine hatchwork lines, to give the impression of better quality.m & french pop/rock Le Tour de France: cycling tactics introduction a general history of postcards other means of dating postcards postcards in the united kingdom postcards in the united states of america postcards in france postage stamp values to aid dating postcards glossary of words and terms end notes You find a pretty and interesting postcard in a secondhand bookshop, maybe in France, or on e-bay.But the correspondent did not date their message and the postmark franking on the stamp is smudged.
