Carte de visites, Stereo Views & Viewers

Carte de visites from different countries around the world. The carte de visite abbreviated as cdv, was a type of small photograph which was patented in Paris by photographer André Adolphe Eugène Disdéri in 1854. It was usually made of an albumen print, which was a thin paper photograph mounted on a thicker paper card. The approximate size of a carte de visite is 54.0 mm (2.125 in) × 89 mm (3.5 in) mounted on a card sized 64 mm (2.5 in) × 100 mm (4 in), but this varies from one country to another.
