Let's make this very clear: One of my hobbies is cleaning up
old engravings, lithographs, and the like. This is one of these - an extensive restoration and cleanup of the 1887 American Civil War artwork "The Battle of Spottsylvania" by Thure de Thulstrup (1848-1930). Printed by L. Prang & Co.
The original, unfixed-up, not-colour-adjusted file can be downloaded at [link]
What did I do? The Library of Congress uses uncalibrated scans, so I fixed the colours, I also cleaned up rips, dirt, and, where I thought it appropriate, some obtrusive artefacting caused by the scanner light hitting the paper grain.
Start to finish, if you want to get this right, it takes about 3-6 hours, depending on size and amount of damage (this one had less damage than some)
