Recently I got a nice book w/ Barks comics in it. Its a collection of Barks' work from 1942 tot 1944 (to get a complete Barks collection I collect Fantagraphics' FCBDL).
I noticed that in the story 'Too Many Pets' (inducks link: W OS 29-3) from 1943 looks "smudgy" where the famous story from the same year 'The Mummy's Ring' (from the same One Shots No. 29 W OS 29-1) looks crystal clear to this very day. If you click on the Carl Barks guidebook 'external link' hyperlink on said inducks page it says "CBL-notes: Retouched, art looks muddy overall.".
Does anybody know why this (long, classic) story, or any Barks comic for that matter, was "retouched"? Did the original print-plate (or what ever that is called) get damaged and did they need to draw it over? Did Disney or Dell preserve the original drawings (i.e. on paper, no photo copy) at all? Does anybody here own the CBL (Carl Barks Library from Another Rainbow publishers, I think).
I know that some "print plates" were lost so Daan Jippes re-draw (or rather: traced from blown up orig. comics material) some stuff in the seventies (the most well known example is 'Race To The South Seas'). Those look quite good. Why was this one re-done, how was it done and why does it look so bad?
I hope that Fantagraphics will find a way to solve this problem. I like the story.
[edit] The other 1943 story from One Shot (or 'Four Color Comics') No. 29, 'The Hard Loser' (W OS 29-2). looks traced too. And in the comments about this story on the site Carl Barks guidebook (www.seriesam.com/barks/comics00.html) I read: "The original 1943 proof pages were discovered. For this reason, the version of the story in "Walt Disney Comics and Stories" No. 551 (1991) is far superior to the Carl Barks Library version". So they were lost and found. The people tracing Barks' original from the comic didn't to a very good job imho.

@Michael: Can you provide some scans of panels from this book?
