Just reprinting a foreword from Chronicles of Conan vol. 1, which doesn't even deal with half the issues included, is indicative of the lack of care DH has shown towards this classic stuff.
As Stu says, only god knows how they got the Tarzan Archives sooo right.

I wonder if DH is so cynical that they are putting these out to make a quick buck, confident in the knowledge that there are still a lot of Conan & Smith aficionados who will multi-dip once they succeed in producing a decent collection.
