That is your definition of first appearance, as you've stated many times, and it's correct from a strict dictionary standpoint. However, as comic books are a storytelling medium, what is collected as first appearances is usually character involvement in a narrative, not Previews ads, CSN stories, flyers, coupons or inter-office memos.
Once again, despite the dictionary, if someone calls you 'bro', don't assume they're your brother.
This definition is not a dictionary definition, it comes right outta Overstreet!
MrWeen Just gotta say I love your sig photo. I just saw the movie you got it from, The Zero Theorem, which is great by the way!
