The National Park Service historian at Appomattox said it's more likely a souvenir copy signed by the same men at that time
- still a significant discovery, he said, even if it's not an official copy.
The Civil War & Underground Railroad Museum of Philadelphia has held the document since the early 20th century. It was pulled out of storage and re-evaluated as officials prepared for the museum's shutdown Saturday ahead of its move to a new building.
Curator Andrew Coldren said he is certain that museum officials knew what they had when the document was donated but its significance was forgotten over time because of a lack of record keeping.
In a 1967 inventory, someone wrote "Copy??" in reference to the document.
Coldren said it had been glued to a cardboard backing and varnished, an apparent attempt to preserve it.
"Old photostat copies from the '20s and '30s are shiny like that, so this is why you'd think this is not a real document," he said.
Coldren said museum officials examining the document recently noticed that the indentation of pens into the paper was visible. He said they also noticed that the ink on the document was darker and lighter in places, as would be expected with the pens used at the time. The lines on a photostat would be of consistent darkness.
"You can see where they're dipping the pen in to get more ink," he said.
Details of the terms and conditions of the surrender were worked out by six men the day after Lee and Union Gen. Ulysses S. Grant agreed on the broad terms of the surrender.
Three copies were made, according to the memoir of Union Gen. John Gibbon, whom Grant put in charge of working out the details of the surrender.
Gibbon kept one copy, according to his memoir and a letter he wrote to the Maryland Historical Society in Baltimore when he donated his to the society. Another copy was sent to Grant's headquarters and is now in the National Archives.
By process of elimination, museum officials believe they have the Confederate copy.
Patrick A. Schroeder, historian at Appomattox Court House National Historical Park, said that while there were three official copies, "it doesn't mean that there weren't more copies made."
Schroeder, who saw a photograph of the document, said the stationery looks more like the paper soldiers used to write letters to their loved ones than the paper used for legal documents.
