I am not associated with the seller nor the KIRKHAM line, but thought this site would like to know about the copy of the photo being auctioned off at eBay now:
"Vintage Photo of Five Members of the same Family that served in the Civil War from Gilford, Connecticut. Measures 13-7/8”W x 10-7/8”H. This photo is an old copy of either an original tintype or a cabinet card. It is of Issac Kirkham and his four sons Leverett, Guilford, Austin and Calvin. They are identified on the back as to who they are and when they were born. Three of them have swords and one has a musical horn (love to get that). Original photo was taken while there were serving in the military. All five of the men survived the war and returned home (Found all of them in the book Catalogue Connecticut Volunteer Force).
Condition: Photo is excellent with clear images. I would guess that this photo is probably 50-60 years old"
