Original circa 1861 sixth-plate DAGUERREOTYPE of a young soldier wearing a black X patch on his jacket - the patch of the 56th New York Volunteer Infantry.
The daguerreotype is still sealed and appears to be in excellent, undamaged condition - the spots are all on the underside of the glass and can be cleaned off, but I am leaving it to the next owner whether or not to break the seals. Comes in half of a case.
