Can somone post a link to the Daniel Best stuff?  I couldn't find it.

There have been instances of material being redrawn, which I consider completly unacceptable.  I speculate that many of the early Archives may have been traced because they didn't have beater copies to decolor, or the inclination to put in the work.  Technology back then also made digital decoloration pretty costly. I'm not sure a 1992 computer would have the horse power to edit a 600 dpi color scan. I know my old Dell with 32 MB of RAM was dead in the water on large files.

I think one of the worst things that happens is a reprint gets into the publishing schedule, and all the sudden there's this urgency to get it out no matter what the quality is.  I'm guessing that explains a huge amount of the early Masterworks volumes.
