Not a knock on you, obviously, but I can't believe people are considering a solicitation mag a first appearance. I mean, technically, Previews probably has the first appearances of half of new modern characters.
Maybe I should go stockpile whatever issue of previews shows the cover image of NYX #3 or, better yet, Walking Dead #1!! Previews #25896712 - the first appearance of Rick Grimes!
I agree 100%, but I find it silly that Gobbledygook #1 has any value as it just shows an ad for Turtles #1 but a lot of people consider ad placements to be key so
