20th Century Danny Boy has a great blog, and always has great stuff with regards to art and comics. With two posts, recently, he's blown the cover off of what what was quietly being done in the Marvel Masterwork series: art by Kirby, Ditko, Ayers, Klein, and Stone is quietly being redone and presented to us as original. If you don't know that this is happening, then its worth a quick read.
The first post, here, describes reading the fine print and figuring out the scoop, along with finding a dealer who is repping the artists doing the recreations. The second, here, talks about the splash page to Avengers #1 up for auction... and the whole discussion of whether it is really Kirby or not.
Danny Boy also brings up something that I've thought many times: there is no reason to recreate what still exists, and I make a case in point "The Life Of Captain Marvel" trade paperback from a few years ago. Clearly Marvel was using low quality stats, or bleaching out original copies of the comics. The brush work was muddy and degraded. As someone who has lived those books as the best part of my childhood (Captain Marvel #25 - 34 and Marvel Feature #11 & 12 since you asked), having it all contained in one easy to read volume was a dream, and I simply couldn't look at the reproduction. Given that a large part of that Starlin artwork in held by about 4 individuals (and you're reading a blog by one of them), I would certainly be happy as can be to send a bunch of 600 dpi scans to Marvel, for free, so that they could have perfect copies for their files. They just have to ask. Why aren't they doing that for the Masterwork Series?
Remind me to tell the story of the Starlin collectors one day. Kinda funny.
