Thanks for the vote of confidence on my newest purchase, shiver.
Truth be told, I don't really pay much attention at all to dates when determining what "age" a comic should be in. I mean, I do use some vague parameters, but to me bronze horror as a distinctive feel...and that feel could come from 1967, or 1985. It depends.
To me, Alan Moore's first year on Swamp Thing is more "bronze" than half the Marvel horrorbooks of the seventies. I guess I'm more interested in collecting a certain look, mood, story, and tradition than I am in collecting according to dates...
