:::::My particular concern: if you're going to use a poorly "enhanced" copy of a colorized version of poor copy of the original B&W; wood-engraved lithograph that was scribbled on (using the wrong colored crayons) from Grandad's book, and attribute the image to Willy Stöwer  then the reader might "unconsciously assume" that was the way Professor Willy Stöwer intended. (See also,  my discussion here).
