You're repeating already failed arguments, and regurgitating information from "Mike's Amazing World Of Comics" website, which for the last time, itself disclaims that it is not an authoratative source. Still tilting at windmills.
Oh, and Action 23 actually has the earlier copyright number, so you're still wrong about that too.
Oh, and you may want to let DC know what the first appearance of their character is. They also still disagree with you.

Keep tilting Don Quixote. Maybe somebody someone who matters will care.
I'm out.
