Well, not really. But I have read every Charlton comic that featured a character DC later acquired. I just finished the last couple Captain Atom issues last night. So if it ever featured Captain Atom, Blue Beetle (Ted Kord and Dan Garrett), Nightshade, Judomaster, Peter Cannon - Thunderbolt, Question, Sarge Steel, Peacemaker, or Son of Vulcan, I've read it. Anyone have any thoughts on those characters or Charlton comics in general?
