This CDV of an American Indian, photographed by the well known New York City Bowery photographer, Chas. Eisenmann, with his imprint on the reverse. Eisenmann's works date from 1870 to the 1890's and he was famous for photographing the "freaks" of the circuses, sideshows and living museums of the Bowery according to the Ronald G. Becker Collection at Syracuse University. Although this sepia image is faint, worn and frayed it is important due to the social implications, as the American Indian was an oddity, not only to be photographed in the East, but to be put on display (as P.T. Barnum and others did, circa late 1860s.)
Pastel colors on CDV's became popular starting around 1869 which would put this photo in the 1870's timeline. Too bad we don't know this young Native American's name or story.
