When will one of the central Marvel titles be completely collected?
As far as I can tell, this has not happened yet. I really look forward to it, though! To be able to own a story that long in its entirety, even if a good deal of it will be in black and white!
EDIT: In physical form, I mean. I know about those DVDs with the scans.
I'm happy to be corrected on this but Amazing Spider-Man is only missing somewhere between 100 and 150 or so (?) of its 700-issue run, counting the upcoming trades and the B/W essentials. I think. Maybe I read that somewhere, but when you consider the Omnibuses, Masterworks, Visionaires, Clone Saga and other 90s trades and the fact that every issue since JMS' run has been collected it may be the closest thing to a complete set.
