Found a rare first edition 1990s comic book with a bright superhero cover and unusual inside markings at the local community center.

I found a rare first edition comic book from the 1990s at the local community center in Northwest KS. It seems to be in great condition, but I have no idea who it belongs to. It has a bright cover with a superhero and some unusual markings on the inside pages. I really want to return it to its owner, so if you recognize it, please reach out!
