n. (cartes-de-visite, pl.; CDV, abbr.) ~ A photographic print mounted on cardboard approximately 4½ × 2 inches.
Patented by Parisian photographer André-Adolphe-Eugène Disdéri in 1854. The format added a photograph to a visiting card. Cartes remained popular through the early 1880s, when they were superseded by the larger cabinet card. On later cartes, the print is slightly smaller than the card, leaving room for the name of the photographer or studio at the bottom of the card.
