I have a large panoramic photo of my grandfather's troop during World War 1.  We know very little of his experience during that war. His troop number is on back of the photo, although I don't remember it at this time (the photo is presently out of town).  His name was Russell Ellis and was from the southeast United States.  Before I go to the trouble of scanning this oversized fragile photo, I want to ask two questions:    (1).  Does anyone in this group have enough knowledge of that war to enlighten our family of his troop's service.    (2).  Would the scan be of interest to anyone. Email or reply to the group.
