Original, late-1850s, circa 1860 ambrotype of dog standing in profile in front of a plain backdrop. To the right you can make out parts of items/equipment around the studio.
In overall very good antique condition, the main issue being some mat abrasions.. it MIGHT be possible to reset the ambro underneath the mat to conceal most or even all of those abrasions, but I've never tried, to be honest.
