When I was a child, a friend of my older brother gifted me several boxes of his old comic books. OK, it was actually a gift to share with my other younger brothers as well, but I saw it as a gift for me. We got about 300 comic books. We could have used the best comic book sleeves for large collections to protect them. However, we just didn’t think of things like that back then.
Almost all of those comics are in good reading condition today, but they are yellowing and beginning to become brittle. I put them in comic book sleeves long ago, but by that point, the damage had already been done.
