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

[L Verge]

I would question my own claims about getting blood on my parasol, Jim, since it was an evening performance and I would not be carrying a parasol to the theater with me!

Question to my doctors out there: If Laura Keene had that much blood on her dress (supposedly in the area where Lincoln's head had rested) and then the Petersen pillows, towels, etc. were drenched in blood, why have I seen it printed so much that the wound bled very little and that the doctors had to keep removing blood clots in order to reduce the pressure on the brain?
