This is the first cabinet card in the Dobb Long Book, and wow, what a great first impression! This young woman is wearing a gorgeous dress, and with the floral embellishment on the bodice I’m guessing it might be a wedding portrait. The dress looks to be from the late 1880s when you take into consideration the asymmetrical draping of the skirt. She is holding a fan in one hand, and I find it strange that only one foot is showing. Finally, she has a lovely double strand of pearls at the throat.
The photographer was Smith & Kneibus of St. Joseph, MI. I wasn’t able to find much on this photographer, although I found one other photograph by them which has been tentatively dated to 1890.
