1/4 Plate Tintype of Federal Soldier said to be "Nathan Ward" KIA

1/6th Plate Tintype of Federal Soldier said to be "Nathan Ward" KIA. This amazing tintype is sharp with some light blue tinting on the trousers and a great backdrop showing a American Flag with a Union Soldier drawn into the back. There is a pen inscription the back that says "Nathan Ward of Johnsonburg PA- Killed in Action" I have had no luck locating Nathan so the identification could be incorrect or I have just not been able to find him. Non the less this is a amazing Civil War image for any collector with some research opportunity.  Housed in a split spine leatherette.
