CDV of Union Soldier "Bob Johnson" from Hollidaysburgh, PA

CDV of Union Soldier "Bob Johnson" from Hollidaysburgh, PA by photographer Frank Proctor. This image was taken from a larger album of 104th PA Soldiers and thought to be Robert Johnson of the 104th PA Infantry. I am not sure it is based off of other photos of Johnson. This still is a great full standing CDV with potential to be nailed down for sure with further research.
