Rare Large 1850s Ambrotype of a Wooded Cemetery / Graveyard Photo Antique 1800s

Original, late-1850s ambrotype of a grave marker, surrounded by fencing and large trees. Writing is faintly visible under magnification but there's no way I can make any of the words out. Large half-plate, case measuring 6" x 4.75" when closed. Ambrotype is in very good antique condition overall, the top-right area is dark, possibly lack of good lighting at the original location.

Case is complete and intact and in excellent condition. My scans often seem to come out too dark. They should give a good idea of what this image looks like in very good indoor lighting or outdoor daylight.
