reading JLA*Avengeers that came out in 2008, never knew about it til now.
Excellent graphics, and story, using multiple universes, and characters I haven't seen in years (because I pretty much stopped buying comics once I got into buying heavy metal albums in Grade 9).
I doubt anyone who was either a Marvel or DC Comics fan in the 1970s or 80s ever thought a collaboration would take place since they are "rivals"
