This is a cabinet card (roughly 4×6″), as opposed to most of the CDVs I’ve been collecting, which are 2 1/2″ x 4″-ish. Major Littlefinger and his wife are depicted here, circa 1880, on a cabinet card by Eisenmann, “the Popular Photographer” who specialized in photographing the theatrical profession (and by theatrical profession, I mean that in the broadest terms – he not only photographed actors and musicians, but sideshow performers and circus freaks, basically anyone who could be called an “entertainer”).
