Shooting Lincoln: Mathew Brady, Alexander Gardner...

[RJNorton]

The above is from page 303 of American Brutus. My copy is in storage, but I found that page on Google Books (link below). I'm not sure whether Kauffman indicated an original source for the Stanton/Robert Lincoln consultation.

There is an endnote for the last sentence of the paragraph where Robert is mentioned. The last sentence is as follows: "Somehow one proof survived, which Stanton kept in his files."

I checked Jason Emerson's Giant in the Shadows. Jason mentions Stanton visiting Robert daily after the assassination, but there is no mention of the photo being discussed.

I wonder if it is just "assumed" the photo was discussed with Robert. The majority of books I have read just mention Stanton alone as the decision-maker. I never realized the possibility that others may have been brought into the discussion/decision.
