Carbon Paper

Making the Mark - I needed to find out if carbon paper was around in 1898, the setting for my next historic novel, Mark of a Man. In one form or another, it was in use as far back as the 1806, becoming more widely accepted in 1867.  So, I can mention it in my story.

By the way, carbon paper is still available today.
