She appears in over 6 panels and speaks - how is that a cameo? Unless your saying part 5 came out before issue 2.
Panel count doesn't count if you can barely see a character and they are just sitting off to the side. Her speaking part was one minor speech ballon - you are really digging for something to say this is the first appearance.
So you probably think ASM #1 is the first appearance of Cindy Moon (silk) - instead of #4 - modern example
You probably think FF67 is the first full appearance of Warlock - silver example
I could go on and on - collectors, and readers will determine which is Key. Either way I don't see "Daisy Johnson" as a character to hold long term collectability either way.
Just warning those who go invest in modern books during this craze. Do your research. If I had #2 and #5 side by side, I would always read #5 first, invest and or collect in it as well.....won't be doing either but just saying.
After all your evidence, you have convinced me, #5 is the key!!! I just hope I can dump all these worthless SW #2 and get me some Secret War #5, the TRUE KEY, before all these blind and dumb speculators get wind of your intense read, re-read, and then re-read it again case study.
I thank you for all your hard work, especially on a book that you "won't invest or collect". I know it must have been hard to do all that work for us un-informed collectors and ignorant speculators, all for something you obviously don't care about...
Cheers to you 1p36DSA, for being a voice of reason,for all us insufficiently_thoughtful_persons, I just hope your information reaches people in time.
