Lincoln’s last written words

[loetar44]

We discussed Lincoln's last spoken words in another thread. But what about his last written words? I think, there is no real question about this subject. The last word Lincoln ever wrote was a brief note given to George Ashmun (Whig member of the U.S. House of Representatives from Massachusetts), shortly before 8:00 pm April 14th, 1865, just minutes before Lincoln started for Ford’s Theatre. "Allow Mr. Ashmun and friend to come in at 9 A.M. tomorrow. A Lincoln. April 14, 1865." I suspect this was penciled hurriedly. Now my question(s), hoping there is someone who has the answer(s). (1) On what was this note written? Was it a card or a piece of paper (not very large). (2) where is this note now? (3) Is there an image of this note existing? Thanks.
