SoCalNacho Posted May 10, 2018 Share Posted May 10, 2018 I have started to transfer some of my 80’s comic books to new Mylar bags and I noticed that you can slightly make out the ad from behind the front cover. This is only visible on a few. Is this normal part of the aging process? Link to comment Share on other sites More sharing options...

Bleed through or seeing the inside of covers is normal and doesn't affect grade. jaydog, SoCalNacho and The Lions Den 3 1 Link to comment Share on other sites More sharing options...
