General Hays and staff, Virginia 1864. I have found one other example as part of the Maine Historical Society records, Maine Memory Network. I've included images of that as well. If I were to guess, several members of the 17th Maine probably received copies.
There is staining to the lower corner, mostly on the mat. 9.75x11.5 mat exterior. 6.5x7.75 image size. This is an authentic antique image and not a modern reprint or digital reproduction. The mat has a couple small cracks along the bottom edge, one of which is shown in the photos, the other being hard to see or capture.
