NARA takes the Lincoln Pardon of Sergeant Major Adam Laws, the Only Known Pardon of a Black Civil War Officer

NARA has the document. They should be happy. Everyone should go to NARA and look at it. What a waste. Filed away to be seen by a few people a year.

If you have any dated government paperwork, regardless of provenance, do not put it up for auction or you will lose it and will not be paid for it.
