This really does not make sense.
There are some people on these boards who insist treasuries, magazines, paperbacks, and other non-pamphlet formats with comic book content are not comics. So if a character appears in a comic magazine first and the character appears again in a traditional sized comic book, the traditional sized comic book is the first comic appearance of the character. Look at the first appearance of Rocket Raccoon for another example.
I know, but this does not change the fact they are comics nonetheless.
Some collectors' tastes do not change a fact. They may be less collected but they will still be first appearances (not talking of R.R., as I have never read the original stories, but speaking in general).
