Today’s image is simple- a tintype head-shot of a young lady, circa 1866-1868. She has no back mark.
We can make out the drop of her armsyce, as well as the stitching line down the front of her bodice. Her bodice closes with hook and eyes and decorative fabric covered buttons. Her collar is crochet and closes with a broach at the center Her hair is arrange low, and appears to be covered with a net.
