"Marvel Masterworks Comic Book Art
For Sale:

This section features original art by artist Michael Kelleher that has been authorized, commissioned, approved by Marvel Comics, and published in their Silver Age Marvel Masterworks anthologies. These are exact recreations of the original works created by legendary artists Jack Kirby, Steve Ditko, Don Heck, John Buscema and many others.

Each drawing measures 14 x 17 inches and was painstakingly reproduced to mimic line-weights and styles of the original artists and inkers.

These are not simple recreations made for fans and collectors. Marvel Comics has gone to great lengths over the past few years to give fans EXACT reproductions of the Silver Age stories that made Marvel famous. Often times the film that was used in the original printing process was either lost, damaged, or altered, so a new version must be created. This is an incredible opportunity to own original artwork of some of the greatest comics ever published!"

should these volumes contain only the original comics, or is it ok for pages to be completely redrawn? it appears that Kirby,Colan,Buscema and Ditko have all had pages redrawn.

jings, i had no idea this was widely used,the masterworks site has an interview with the editor of the masterworks http://www.marvelessentials.com/news/int_cs_1206.html

5: What percentage of art restoration in the Masterworks needs to be redrawn by hand by folks like Mike Kelleher? (Amazing job he's doing, by the by.) Is it on the order of a page or two per volume? More?

CORY: I couldn't give a direct percentage across the Masterworks. It's something that varies widely. The Golden Age books are all fully reconstructed from copies of the original books because none of that material exists in Marvel's archives any longer. Back in the '40s no one could have guessed that almost 70 years later people would be pining for these stories!

Meanwhile back at the ranch, the Atlas Era has proven to be either completely hit, or completely miss so far. These issues have either been intact in the film library and in great shape, or completely missing. For instance, Marvel Boy #1 and #2 were found and in sparkling condition (the earliest finds from our film warehouse yet, which is not to say there isn't earlier material, we just haven't gotten around to reprinting it yet); however, Astonishing #3 and #4 were completely missing.

For the Marvel Age, it varies. Some volumes require no full reconstruction. Others require two or three pages, and others, say where a complete story is missing, 20 plus pages. Earlier material tends to be in poorer condition. Most likely because it was duplicated over and over again throughout the '60s, '70s, and '80s for various reprint comics. I've heard word that the first generation photostats were sent out West for use in the 1960s Marvel Super Heroes cartoons. "

This is news? It was a big part of the "Theakstonizing" process of the early DC archives, and I've personally talked to an inker who said that he worked for a while (with Will Eisner's approval) on doing the same thing with old Spirit splash pages (restoring line weights etc:) for the DC collections.

It's art restoration applied to comics (and yes, that's how art restoration is done on old canvases, too. They get a talented artist to try to recreate the parts that have gone missing)
