Proto-postcards

I have a new collection: Victorian Carte-De-Visites (CDVs) and Cabinet Cards from the 19th century! (Three of anything makes a collection!) CDVs, introduced in 1859, were essentially photographic calling cards. A few years later, slightly larger albumen prints called Cabinet Cards became all the rage. Here's one that I just scored on ebay and one that I lost (dammit). Link Discuss
