It's a good question, and one I have asked DC war collectors many times.
I do know one collector in the midwest who has a full set of DC war books.... and he's been collecting for many, many, many years (ie, was buying 10-centers off the shelf and still has them in his collection). I also recently sold some books to a collector on the east coast who says he is 5 books away.
Chris Pedrin is rumoured to have two complete sets.
There are a couple of DC completists who, by dint of having complete DC collections, must have full war runs.
By my estimation, ten... maybe 15 complete collections of these books. Hard to say, though, because there are enthusiastic fans of these books who operate outside of fandom in general.
I hope to have them all in about 5 years! I'm actually enjoying these early books much more than I had anticipated... there are some very, very good art jobs in them.
Shep
Why would Chris Pedrin own 2? That's somewhat mind boggling! I guess automatically we can count Ian and Christine since they both own "all DC's". I would guess your right, maybe a dozen? Even that numger sounds high considering some of those books have to be pretty scarce.
How many books in total make for a complete big 5 collection?
