| The carte de visite or CDV (also carte-de-visite) was a type of small photograph which was patented in Paris, France by photographer André Adolphe Eugène Disdéri in 1854.[1] It was usually made of an albumen print, which was a thin paper photograph mounted on a thicker paper card. The size of a carte de visite is 2.125 × 3.5 inches mounted on a card sized 2.5 × 4 inches. It was made popular in 1859 in Europe, and from 1860 in the United States. |
