The only Timely Golden Age material I've ever seen has been from reprint books: Fantasy Masterpieces, the Masterworks editions, the Golden Age of Marvel tpbs, various reprints including the Milestone Edition of Captain America 1, the odd 70's comic here and there, so I am unable to compare the original printings to any of the reprints. Any lack of quality in the printing of the material is something I'm oblivious to other than saying to myself "that looks kind of cheesy or dark or weird ... but at least I can read these stories". If all Marvel did was scan the books into a computer and then print the stories from that, it would be good enough for me.
I wonder why they don't follow the old 'Hard-cover' for hardcore fans and soft-cover down the road for price conscious collectors?
Maybe the demand just isn't there to publish the material in mutliple high-priced volumes. I would prefer to see something along the lines of "Fantasy Masterpices" where there was a mix of features in every book. Hey, if AC Comics can make a decent amount of money reprinting Golden Age comics in B&W, there has to be enough support for Marvel's "Big Three" (and friends) to be reprinted in their own monthly title ... in color.
The big problem with a book like that is that you need to figure the cost per issue. Call each 68 page issue equal to 3 current issues (23 pages of story.) Multiply that by 12 issues, you've got 36 issues of content.
The only problem with that line of thinking is that you're ommitting the fact that the stories were, aside from any "art recreations", bought and paid for over 60 years ago. Unless Marvel will be sending-out royalty checks to all of those creators' families, I can't see where it's justifiable to charge almost the same amount of money per page as they do for new comics. It should easily be half that since, using today's pay scale, they're not paying hundreds of thousands of dollars for a writer and/or an artist to produce that amount of work (assuming a writer and artist could actually stay on one book long enough to produce 36 issues of material). What are they paying for then? A hard cover? Shiny paper? Use newsprint, it's cheaper (if it wasn't, newspapers wouldn't be using it, would they?) and the stories read exactly the same way as they would on the fancy paper. And who the heck wants to handle an 800 page comic? Comics are meant to be "light reading material", not something that becomes the equivalent of decent upper-body work-out.
