Gettysburg Campaign African American Albumen Group Photo 3rd Regiment US

Identified Civil War African American Albumen Group Photo in Ornate Frame!
This photo is of Capt. Howard and group. Office of Assistaant Quartermaster army of Potomac. Fairfax Court House June 1863 of the Gettysburg Campaign. All the names of the men are written on the bottom of the image which I have been unable to find anywhere else! Meaning that this could be an another piece to the puzzle of who all is in the photo! The original glass negative remains in the Library of Congress making this a spectacular piece of history.
