This. This. A thousand times this.
I would argue that Aquaman reached such dizzying heights of lameness that he entered a kitschy wormhole, came out on the other side, and is now unmitigatedly amazeballs.
A founding member of the Super Friends stars in his first solo book. How is that not a key?
Saying something a thousand times doesn't make it any more true than one or a million. I get you are trying to emphasize a point, but the reference doesn't legitimize your statement.
Things like "first tryout issue" and "first cover outside JLA" are not reasons for a book to be considered key. They aren't even close to a realistic justification of what could qualify a book to be key. "First appearance" or even "first appearance in X age" are reasons to be considered some level of "key." Beyond that there is a very short list that includes things like: first famous artist or writer and significant plot or social issue...not "first tryout."
FYI - his first solo book is Aquaman 1, not Showcase 30.
I was actually making a reference to the quote "Yes! Yes! A thousand times yes!" because I need a little variety in my life, and typing +1 all the time bores me.
I also thought that Showcase #9 was an excellent example, because Lois had appeared in more than 300 comics at this point, but she never had her name featured in the title before. The same thing happens for one of DC's most important superheroes(one of the most well known comic book characters in existence) in showcase #30; Aquaman is finally ready for prime time.
The way I view this is that Showcase #30 is a key book in my collection and it isn't in yours. I'm totally fine with that.
As a collector, the books I search for are important to me for my own personal reasons and I only care about their value because it helps me prioritize my future purchases. Obviously, I'd much rather fill a hole in my collection before the book I need triples in price. Also, I'll always search for underrated books that I think will earn me $$$ in the future, because it's a fun way to turn your comics into more comics. Other than that, who cares?
Honestly, I'll take it a step further and say that one of the great pleasures of joining these boards is discussing your shared love of comic books. Not everything needs to be sunshine and roses, friendly debate can be fun too, but why do you care if someone else considers something a key? There is no right or wrong answer here.
