I have no idea why this is a key (I'm new to comics outside of knowing DC and Marvel) but wow, that is an amazing cover and an awesome book! Congrats!
Thanks! Comico was a much beloved indy publisher for us children of the 80s. Primer 2 was THE issue to own from them, and has remained a fan favorite even after 30 years. It was the first appearance of Matt Wagner's Grendel, the character equivalent of, I guess, Wolverine for them. All early Grendel appearances were going for big money back then. But this issue was the crème de la crème. And yes, very cool cover. Black border makes it especially difficult to find without spine tics & creases. Tiny print run as well. All adds up to being a key issue from that era.
And some people think a spine stress automatically excludes a book from 9.8 status. There is a stress right on the FC of this.
And some people are just haters...
