Although I have been collecting for a few years I still consider myself a novice when it comes to overall comic knowledge. One issue I am having is First appearances. Most are not debatable but some are including Wolverine. Regardless of anyone's opinion the money is on 181 and that it not debatable. For other book that do not get as much attention when their first appearances are debated a novice like me never really gets an answer. Specifically, I am looking for the first appearance of Mace Windu in comics. I have used several tools. (key collector, comicbookrealm, facebook, ect) but came up with different answers. 1) Does anyone here know the first appearance? 2) Does cgc have an official list of what they recognize as first appearances?
