The “rubber box” or did Laura Keene indeed held Lincoln’s head?

[RJNorton]

My best guess is to agree with you. But, like so many Lincoln assassination facts, I am not 100% certain.

More and more I depend on Tom Bogar's Backstage at the Lincoln Assassination for details not found (or difficult to find) in other sources. Tom makes no mention of Keene going to the Petersen House. Rather he has her going backstage and washing the blood from her face and hands. Then, along with her husband, John Lutz, they "slipped out of the theater by the alley door and made their way east on F Street to their room at the Metropolitan Hotel. No one hindered or detained them."
