I have read a couple issues in the Black Label line. My question is are these considered main DC continuity with the other comics, or are the kind of an elseworlds type of thing.
While exceptions may arise, Black Label comics are generally considered to be outside of the typical continuity.
I believe Black Label is considered alternate universe
Yeah, like Superman Year One or Batman White Knight.
So far the only Black Label book that is coming out that will likely be in continuity is The Three Jokers.
