The photo and story about Stanton's son is in "20 Days", (page 162) and the photo was included in the Nicolay papers donated to the IL State Historical Library. https://www.amazon.com/Twenty-days-Assas...36AQ6VZ228
Also the next page in the book includes four (4) 'Spurious photographs of Lincoln in death. They are all in a reclining position.
So when is this "Old Enough To Know Better" supposed to kick in?
