This whole topic is laughable.....AF15 is KING and the 3rd most important comic book EVER made!! I like the TMNT since I grew up with them but they are no where near being in the league of AF15's.....not even close!! It is like comparing Babe Ruth with an almost no name (Semi good) player of his time or even of our time....it's called insanity!!
Hulk, Iron Man, Flash, Fantastic Four, X-Men, Thor, Ant-Man (TTA27), Justice League Of America (BB28), The Avengers and so on are way more in demand/popular than the TMNT!!
I would not trade any top 10 SA book for a TMNT #1....NEVER!!
In the end TMNT #1 is a cool book to own if you do not have to trade a more important book to own one. I hate putting TMNT #1 down like this because I like the book but when comparing it to AF15 or any other key SA book it simply makes no sens at all!!
