Wet Plate Wednesday: Poor Broken Ambrotype

This ruby ambrotype has been in my collection for at least 10 years, but she doesn't get to come out to play.  Broken and poor quality, I wonder about her story. Ruby ambrotypes are developed on purple rather than clear glass and usually of better quality and yet here we are with a barely visible image.  I have enhanced her image dozens of times to get a better look, but this is the best I have come up with so far. Is it actually taken outside or in front of a backdrop?  How did she survive all these years in pieces and so difficult to see? Is it an image taken of an image, or a novice photographer with little experience?  Some how I feel she is special, or special to me any way and I will continue trying to get a better view as technology improves.  One day, I will get a better glimpse of this early 1860s beauty.
