Phil is correct...it's a photo pasted onto a mount.....(cdv)

Carte de Visite photographs--small albumen prints mounted on cards 2-1/2 by 4 inches--were wildly popular and made for decades in countries around the world. The format was an international standard; for the first time, relatives and friends could exchange portraits, knowing they would find a place in the recipient's family album--whether that album was located in Brooklyn, Berlin or Brazil. In addition, unlike earlier photographs made with such processes as the daguerreotype and ambrotype, cartes de visite could be sent through the mail without the need for a bulky case and fragile cover-glass. Their small size also made them relatively inexpensive, and they became so widespread that by 1863 Dr. Oliver Wendell Holmes would write, "Card portraits, as everybody knows, have become the social currency, the 'green-backs' of civilization."
